The document discusses the design and working principles of an inverter, which converts direct current (DC) to alternating current (AC). It details the components involved in the inverter circuit, including MOSFETs, batteries, capacitors, and ICs, as well as their function and applications. The document concludes with the successful simulation of the inverter design using Proteus software and cites several references for further reading.

4. A device that converts direct current
electricity to alternating current either for
stand-alone systems or to supply power to an
electricity grid

5.  The working of an inverter is, it converts DC
to AC, and these devices never generate any
kind of power because the power is
generated by the DC source. In some
situations like when the DC voltage is low
then we cannot use the low DC voltage in a
home appliance. So due to this reason, an
inverter can be used whenever we utilize
solar power panel

8. The MOSFET is a three-terminal (gate, drain, and source)
fully-controlled switch. The gate/control signal occurs
between the gate and source, and its switch terminals are
the drain and source. The gate itself is made of metal,
separated from the source and drain using a metal oxide.
This allows for less power consumption, and makes the
transistor a great choice for use as an electronic switch or
common-source amplifier.
In order to function properly, MOSFETs have to maintain a
positive temperature coefficient. This means there’s little-
to-no chance of thermal runaway. On-state losses are
lower because the transistor’s on-state-resistance,
theoretically speaking, has no limit. Also, because
MOSFETs can operate at high frequencies, they can
perform fast switching applications with little turn-off
losses.

9. MOSFET stands for Metal Oxide Silicon Field Effect
Transistor or Metal Oxide Semiconductor Field Effect
Transistor. This is also called as IGFET meaning Insulated
Gate Field Effect Transistor. The FET is operated in both
depletion and enhancement modes of operation.

10.  Improved switching speeds
 Improved dynamic performance that requires
even less power from the driver.
 Lower gate-to-drain feedback capacitance
 Lower thermal impedance which, in turn,
has enabled much better power dissipation.
 Lower rise and fall times, which has allowed
for operation at higher switching
frequencies.
 MOSFET is a low cost

11. A battery is a device in which we can use the energy as a
source of power. The energy which store in battery is in
the form of chemical energy which is converted into
electrical energy. In this circuit we are using 12 volt
battery for simulate our circuit

12. A capacitor is a component which has a ability to stores the
energy in it. The store energy is in the form of electrical
charges..

13. There are 14 pins available on the IC where Vss stand for
ground pin and Vdd is voltage supply pin. There are six
inputs including, trigger, astable, external reset and
retrigger.

14. A potentiometer is a three-terminal resistor in which the
resistance can control the flow of electric current. In
short we can say that it’s easily to control the flow of
electron

15. A resistor is a two-terminal electrical component which is
used in a circuit element. Resistors are used to reduce
the flow of current and also adjust the signal levels

16. A transformer is a device which flow the electric energy
from one terminal to another terminal. We can say that it
can reduce or increase the voltage of an AC

18. CD 4047 is a low power CMOS astable/monostable
multivibrator IC. Here it is wired as an astable
multivibrator producing two pulse trains of 0.01s
which are 180 degrees out of phase at the pins 10
and 11 of the IC. Pin 10 is connected to the gate
of Q1 and pin 11 is connected to the gate of Q2.
Resistors R3 and R4 prevents the loading of the IC
by the respective MOSFETs. When pin 10 is high
Q1 conducts and current flows through the upper
half of the transformer primary which accounts
for the positive half of the output AC voltage.
When pin 11 is high Q2 conducts and current
flows through the lower half of the transformer
primary in opposite direction and it accounts for
the negative half of the output AC voltage

20. Adjustable-speed ac motor drives.
Uninterrupted power supplies (UPS)
Running appliances of ac used in an
automobile battery.
power transmission industry such as
reactive power controllers and
adaptive power filters

21.  Can be an energy efficient way of
changing voltage.
 Can step voltage up or down.
 Can provide electrical isolation between
input and output.
 Can provide an AC voltage from a DC
source.
 Can smooth out random variations in
input voltage

22.  Require rectification and smoothing on the
output if the output is to be DC.
 May produce radio interference or audible
tones.
 May produce AC at a non-specific frequency.
 In certain types of UPS the inverter may need
to phase synchronized to the input AC power
to ensure a spike free switchover.
 May produce excess output voltage under no
load or very light load conditions

23.  Inverter is used to covert DC to AC..
 Design ,construction & testing the MOSFET
inverter successfully done by simulation
using proteus
 Accurate analysis is possible with proteus
software
