microcontroller inverter

hi all,

i want to know how can the microcontroller is used to control an inverter.please give me any recommendations about this subject.



regards,

usage of dsp in inverter

For inverter control u can use DSP for effective realtime operation..

PIC16F72 is very much suitable for making an inverter

It has to perform following tasks

Genetare complementary pwm singnals ( Push pull configuration)
TO generate pwm use TIMER2 and use PR2 TO vary the pulse width

Analog inputs are
1) Mains sense signal
use stepdown transformer and scale to 0-5v level

2) Inverer o/p voltage signal
use stepdown transformer and scale to 0-5v level

3) Battery voltage sense signal
Use resitor network and scale it ot 0-5v level

4) Relays and driver to for change over from mains to inv mode and vice-versa

5) Suitable leds for status indication

Hi
1) May be for speed of operation
2) Used mainly in ONline UPS ( for sine wave o/p)
3) Multiple DC-DC conversion
4) Most of the DSPs have builtin multiple PWM o/p modules(Dspic)
1) can be configured for driving pushpull
2) or H-bridge driving
5) Programmable dead band options is present in Dspic

Also

6) Algorithms lik PID can be easily be implemented

Refer to Triple conversion Online UPS application note from TI site

Any url for DSP based controller..
