    Half Bridge SMPS using SG3525+IR2110, Output not changing with duty cycle

    Hi, I have built an smps, Half Bridge using SG3525 + IR2110. It works fine - Except for changing(control) the output voltage by changing the duty cycle. The nominal dc voltage is 270. Half is 135v The transformer core is E42/21/15 Primary windings : 20 Secondary 4+4 : gets 32v - needed...

    12V to ±80V adjustable isolated half bridge converter.

    I really appreciate if someone can help me a bit with this project. Its a half bridge topology DC-DC converter that takes 12V on the Input and transphorms it into a simmetrical 80V output (Maximum). The output voltage will be adjustable from ±18V to ±80V. I am using the SG3525 IC for this...
