Okay, these are really good questions; I operate at a fixed duty cycle around 45% as of now, making the on time about 23 us, and the off time 27. The transformer inductance is 43 uH. No idea about the saturation (no idea how to measure it), but judging by the overshoots I get with no zeners, I...
Good day everybody
I am trying to make a transformer isolated switch for an IGBT; a part of the circuit is shown below.
It includes a low-current side switched by IRF644 MOSFET (I just have these on hand) and a home-wound transformer, all driven by SG3525.
The secondary winding is loaded onto...
