Full bridge Output not varying
Posted by: Naveeng
on
I have designed a full bridge converter. I am stepping down the voltage from 350V to 60V. I am gate pulses with the phase shift.
But the output is not varying even i have varied my duty cycle. I am getting a constant output of 30V.
My transformer design has a primary of 30 turns and secondary of 7 turns.
Can you people please let me know where i have i have done mistake and help me.

Hi Naveeng,
Please provide the captured waveforms of the gate voltages, primary coil and secondary coil voltages and the primary coil current. These will provide information or hint what was causing the problem.
