Three Phase 180 degree mode inverter

The inverter is designed with the help of GTO's for best performance.

The Gto's are triggered as per the following sequence

for conversion process i'll just tell you an easy trick. we have theta=omega*t...so t can be written as theta/omega..

if the angle is 60 degree and frequency is 50 hz..then timeperiod =1/50 and the delay is t= 60/2*3.14*50 ...

Pulse Width : 180/360 =50&

If u hav got any doubts,please contact me..
