5. Uncontrolled Rectifier
Rectification: The process of
converting the alternating voltages and
currents to direct currents.
Rectifier: AC to DC.
IN4008 diodes are used as in this
rectifier

7. Step Down Chopper Circuit
Fixed DC Supply to Variable DC Supply

8. Chopper Control
Controlling the voltage level of the dc
Link can be done by changing the PWM
signal through the microcontroller.
A push button switch is used to increase
or decrease the Ton period of a constant
frequency pulse.

9. PA6 and PA5 are outputs from microcontroller.
XOR: High frequency of variable width is
generated by the microcontroller and the XOR
gate.
Variable width pulse is applied to the gate of
MOSFET through an Opto-coupler

10. Optocouplers
LED for emitter
Air as barrier for isolation
Phototransistor for detector
Transformer is similar, but only for AC
Optocoupler can be used for DC

11. Inverter:
Inthis study two power electronics
switches ( MOSFET’s) have been used to
convert the dc to ac voltage.
The frequency is fixed and variable
output voltage is obtained by varying the
D.C link Voltage by means of the pulse
width of the chopper switch.

13. H bridge operation.
 It can be seen from inverter circuit
diagram when T1 and T2 are gated with
positive voltage signal, T3 and T4 are OFF
by the zero gate voltage signal and vice
versa.
 The four MOSFET's of T1,T2,T3 and T4
shoud not be Turned ON at the same
instant of time.

• Squirrel cage rotor
• 3 to 4 HP applications
• Household appliances: fans, washing
machines, dryers
Electromagnetics
Rotor
Stator

16. Induction motors working
 Electricity supplied to stator
• Magnetic field generated that moves around rotor
• Current induced in rotor
• Rotor produces second magnetic field that opposes
stator magnetic field
• Rotor begins to rotate

18. AVR Microcontroller
Groups: The AVR line is divided into to major
groups; Tiny and Mega, with some additional
special function versions for specific applications
such as lighting, automotive, battery management,
rf comms, and LCD drivers.
Tiny: 1 to 8KB FLASH, 32 to 512 Byte RAM, 0 to
512 Byte EEPROM, 6 yo 18 IO pins.
Mega: 4 to 256KB FLASH, 0.5 to 8KB RAM, 1/4
to 4KB EEPROM, 18 to 86 IO pins.

19. AVR MEGA8535 MicroController
 RISC core running single cycle instructions. 32
general purpose registers. On chip hardware
includes: Internal oscillators, timers, UART, SPI,
USB, pull-up resistors, pulse width modulation,
ADC, analog comparator, up to 4x40 LCD
drivers and watch-dog timers. On chip in-
system programmable Flash and EEPROM. 1.8-
5.5 Volt power options. Software controlled
frequency and sleep modes with fast wakeup

20. Advantages of Atmel AVR
 Cost.
At the moment, the very lowest-price
microcontroller available from any
manufacturer is the RS 150.
 Speed:
Not only are most AVRs capable of 20MHz
(even really cheap ones like the
ATtiny25/45/85 and ATmega48), but they
actually run at near 20 MIPS;
In addition, with the better addressing
modes and registers of the AVRs, most
operation can be done in only one instruction,
where it often takes more than one
instruction to do the same thing on a PIC
Controller.

21. Advantages of Atmel AVR
Peripherals
Many Atmel AVR µcontrollers, like
many Microchip PIC µcontrollers, have a
built-in 10 bit ADC. Some have LCD or
USB drivers.
Easy Programming
All customizable code written in ANSI-C
and thus easier to maintain.
Modular concept: easier to integrate into
existing designs.
Slightly smaller code size in spite of high
level language modules.
