Hi ,
Iam trying to do an open loop ,simulink simulation of a phase shift full bridge converter. i used an ideal transformer as a start .input is 160V and output required is 24V.iam providing the phase shift by manipulating the phase delay in pulse generators for providing gste pulse.The issue that iam getting is that i fixed the transformer turns ratio to be 5 which is a design requirement ,What ever change i manually provide to the phase shift it doesnt make any change in the output voltage.

Hello adam18! In my opinion the phase delay time must be less than the pulse width, i.e. < 1/200e3 (sec)
