INTRODUCTION
A chopper is a static device which is used to obtain a variable dc voltage from a
constant dc voltage source. A chopper is also known as dc-to-dc converter. The thyristor converter offers greater efficiency, faster response, lower maintenance, smaller size and smooth control. Choppers are widely used in trolley cars, battery operated vehicles, traction motor control, control of large number of dc motors, etc….. They are also used in regenerative braking of dc motors to return energy back to supply and also as dc voltage regulators.
Choppers are of two types
• Step-down choppers
• Step-up choppers.
In step-down choppers, the output voltage will be less than the input voltage
whereas in step-up choppers output voltage will be more than the input voltage.
Classification of Choppers:
(a) Depending upon the direction of the output current and voltage, the converters can be classified into five classes namely Class A [One-quadrant Operation] Class B [One-quadrant Operation] Class C [Two-quadrant Operation] Class D [Two-quadrant Operation] Class E [Four-quadrant Operation]
(b) Based on the output voltage of the output, the choppers are classified as
(i) Step-Down Chopper In this case the average output voltage is less than the input voltage. It is also known as step down converter
(ii) Step-Up Chopper Here the average output voltage is more than the input voltage. It is also known as step up converter
(iii) Step-Up/Down Chopper This type of converter produces an output voltage that is either lower or higher than the input voltage
(c) Depending upon the power loss occurred during turn ON/OFF of the switching device, the choppers are classified into two categories namely
(i) Hard switched Converter Here the power loss is high during the switching (ON to OFF and OFF to ON) as a result of the non zero voltage and current on the power switches.
(ii) Soft switched or resonant converters In this type of choppers, the power loss is low at the time of switching as a result of zero voltage and/or zero current on the switches.

Simulation Analysis of Ac/Dc Adapter Under Zero No-Load Power Consumption usi...IJPEDS-IAES
The burst-mode control is generally used to regulate the output voltage of the ac/dc adapter under light or no-load condition. Although the burst-mode control reduces the switching loss, the control-IC and the feedback circuit at the output side still consume a large amount of power. In order to further reduce the power consumption at no-load condition, a zero no-load power (ZNP) ac/dc adapter for electronic equipment with an embedded battery is proposed in this paper. When the proposed adapter is load connected, the operation is same as that of the conventional adapter. At no-load condition, the adapter is totally turned off. As a result the adapter can reduce the no- load power consumption to less than 1mW. Simulation of a 65 W adapter is presented in order to verify its validity
Here an electronic circuit breaker is designed which is based on the current sensing across a series element typically a CT (current Transformer). The current sensed which is compared against the preset value proportional to the voltage by comparator which is inbuilt in arduino to generate an output that drives a relay through a MOSFET to trip the load very fastly.
The concept of electronic circuit breaker came into focus realizing that the conventional circuit breakers such as MCBs take longer time to trip.
The steadily increasing population has more demand and consumption of electric energy in the market as raised and that of equipment’s used like electrical and electronics are also costlier
So to protect the electrical system from overload or short circuit here is one possibility, which is by ultrafast acting electronic circuit breaker
The electronic circuit breaker is based on the voltage drop across a series element proportional to the load current, typically a low -value resistor.
Intelligent Electric Power Management Using Zigbee with Advanced Metering Inf...Akbar Badusha
This project mainly focuses on reduction of power cut and power theft. The main reason for the power cut is shortage of power in the generation unit. We can rectify this problem through our project.
Whenever the generation falls behind a particular limit (it is set initially by EB) the power management system will automatically switched on. Power will be supplied to only the basic necessary equipment (as stated in the priority list) power to other load will be stopped so that huge amount of power can be saved without power cut.
In our project, this is achieved using NS2 software and using ZIGBEE. Whenever generation falls below the particular value, then the load will be automatically switched off based on priority. And it can also be done through an interrupt. Through ZIGBEE command the interrupt will be sent to microcontroller to cut the power to the particular load.
When microcontroller receiving the command, the relay will cut the power to the equipment. So the power will be saved.
In this project,the method to detect and to control the power theft is also stated. Other methods of power theft like damaging, by passing electrical power meter can also be detected and can be punished.
Man power can also be reduced. The power usage of the customer will be automatically updated in the EB station so there is no need of man power to take meter reading in the user side. After every two months the reading will be automatically resetted.
The design of an LED emergency light that switches on automatically when main power fails. Power to the LED is supplied by a battery that keeps charging when the main power is present.

Complete circuit diagram, which is tested successfully, is given.
Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

4. ABSTRACT
The project is designed The UPS helps to "smooth out" voltage, i.e. eliminate peaks that
are over a certain level. When there is a power outage, the energy stored in the emergency
battery keeps the power supply flowing to equipment for a small amount of time (normally for 5
to 10 minutes). Beyond the minutes of autonomy that the UPS supplies, this gained time also
allows the equipment to be switched to other energy sources. Some UPSs can also be directly
attached to the computer (e.g. with a USB cable) so that it can order its own shutting off in case
of a power outage and thus avoid any data loss.

9. 2.1 STATEMENT OF UDP
An uninterruptible power supply (UPS) is a device that protects electronic equipment from
power uncertainties. A UPS is a device that is interfaced between the electric network (connected
to utility power) and the materials that need protecting.
The UPS allows the materials to be switched to emergency battery power for several minutes
in case of electrical problems, in particular during:
Power line disturbances, i.e. a split second power outage that can cause a computer to
restart
Power outages, corresponding to a break in the power supply for a given amount of time
Overvoltage, i.e. a nominal value greater than the maximum value needed for the normal
functioning of electrical appliances
Undervoltage, i.e. a nominal value less than the maximum value needed for the normal
functioning of electrical appliances
Voltage spikes, i.e. high amplitude transient (short-term) overvoltage. These spikes are
caused when powerful devices are stopped or started and overtime can damage electrical
components
Lightening, which is a source of extreme overvoltage that occur suddenly during bad
weather (storms)
Most electrical disruptions are tolerated by computer systems. However, sometimes they can
cause data loss and service interruptions and even material damages.

2.3 COMPONENT LIST
11. 3.1 BLOCK DIAGRAM
The ever increasing importance of computers in industry and commerce will increase the
need for quality, high stability and interruption free power supplies.
A clean ac power source is the fundamental to the operation of most sensitive electronic
equipment, and many new and sophisticated circuits are designed to overcome the effects of
disturbances normally found in the mains ac supply.
In order to protect a sensitive system from power losses and blackouts, an alternative
power source is required that can switch into operation immediately when disruption occurs. An
interruptible power supply (UPS) is just such an alternative source. A UPS generally consists of
a rectifier, battery charger, a battery bank and inverter circuit which converts the commercial ac
input into dc suitable for input to the battery bank and the inverter. The rectifier should have its
input protected and should be capable of supplying power to the inverter when the commercial
supply is either slightly below the normal voltage or slightly above.
12. 3.2 CIRCUIT DIAGRAM & ITS WORKING
WORKING
This is the circuit diagram of a simple UPS that can deliver 12V unregulated and 5V
regulated DC. The transformer T1 steps down the mains voltage to 12V AC and then the bridge
B1 rectifies it. The rectified signal is smoothed by the capacitor C1.When the mains supply is
available the battery will be charged via diode D3 and the regulator IC gets supply via diode D5.
12V and 5V DC will be available at the output terminals. When mains supply is not available the
battery supplies current to the regulator IC and to the 12V DC terminal through diode D4.Also,
the diode D3 blocks reverse flow of current during battery mode. Capacitors C2 and C3 acts as
filters.
working principle of UPS From basic principles in terms of application, UPS is a device
that contains stored energy in order to inverter as the main component, regulated stable
frequency output power protection equipment. Mainly by the rectifier, batteries, power inverters
and static switch of several components.

14. 3.3.1 TRANSFORMER
Transformers convert AC electricity from one voltage to another with a little loss of power.
Step-up transformers increase voltage, step-down transformers reduce voltage. Most power
supplies use a step-down transformer to reduce the dangerously high voltage to a safer low
voltage.
FIG 2.1: A TYPICAL TRANSFORMER
The input coil is called the primary and the output coil is called the secondary. There is
no electrical connection between the two coils; instead they are linked by an alternating magnetic
field created in the soft-iron core of the transformer. The two lines in the middle of the circuit
symbol represent the core. Transformers waste very little power so the power output is (almost)
equal to the power input. Note that as voltage is stepped down and current is stepped up.
3.3.2 VOLTAGE REGULATOR 7805
15. The purpose of a voltage regulator is to keep the voltage in a circuit relatively close to a
desired value. They are one of the most common electronic components, the are used since a
power supply can produce high current that can damage one component/or whole of the circuit.
Voltage regulators have variety of functions. It all depend on the application. Voltage can be
changed by varing the source voltage or Varyng the input impedance of the regulator being used.
Features
• Output Current up to 1A.
• Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V.
• Thermal Overload Protection.
• Short Circuit Protection.
• Output Transistor Safe Operating Area Protection.
3.3.3 RECTIFIER
A rectifier is an electrical device that converts alternating current (AC), to direct current
(DC), current that flows in only one direction, a process known as rectification. Rectifiers have
many uses including as components of power supplies and as detectors of radio signals. In this
project, a bridge rectifier is used because of its merits like good stability and full wave
rectification. In positive half cycle only two diodes( 1 set of parallel diodes) will conduct, in
negative half cycle remaining two diodes will conduct and they will conduct only in forward bias
only.
16. 3.3.4 FILTER
Capacitive filter is used in this project. It removes the ripples from the output of rectifier
and smoothens the D.C. Output received from this filter is constant until the mains voltage and
load is maintained constant..
The simple capacitor filter is the most basic type of power supply filter. The use of this
filter is very limited. This filter is also used in circuits where the power-supply ripple frequency
is not critical and can be relatively high. Below figure can show how the capacitor changes and
discharges.
17. 2.3.5 BATTERY
UPS battery is used as a storage energy device, which consists of several cells in series, with
a capacity to maintain its size determines the discharge (supply) time. Its main function is: When
the electricity is normal, the energy converted into chemical energy stored in the battery internal;
when the electricity fails, the chemical energy into electrical energy provided to the inverter or
the load.
18. 3.3.6 STATIC SWITCH
static switch also known as static switch, which is a non-contact switch, is to use two
SCR (SCR) reverse parallel composition of a communication switch, its closed and disconnected
from the logic controller control. Conversion and the model is divided into two kinds of type
and. Conversion-type switch is mainly used for two-way power supply system, its role is to
achieve all the way to another road from the automatic switching; and model switch is mainly
used for parallel inverters with electricity or more inverter.
