So got my SG3525 driver circuit completed and checked the output with my scope, i am getting two opposite phase square waves, 20khz each, 50% duty cycle. I tried many times to create a gate drive transformer and none were outputting the correct waveform, i have tried multiple "salvaged" toroids and a few E cores, tried different numbers of turns and all with the same result:
Here is the output of the SG3525:
The voltages are the same just offset a little
Failed Transformer attempts:
and:
the two failed attemtps were two different toroids, i recevied the same resultes from the e cores i tried, what is my problem? i am using more than enough turns to prevent saturation, also the gate drive transformer attempts only have one primary and one secondary in a 1:1 ratio
