What do, not does, how do I edit titles ??
I have seen a few isolated forward converters, of the type with 3 windings, where across the primary, there are 2 rectifier diodes, like this, pic of schematic below.
I know only the basics of magnetizing currents, and of Volt*seconds.
WRT to the neg. of the rectifier, between D8/9 I have measured over 328Vdc on a good DMM, when I was pulling 1.15A from Vstby. When the mosfet turns off, and the L1 current in L1 wants to continue, does a small reverse current run through D8 to demagnetize L1 ? And or does it get transferred into L2/3 ?
I was looking at the waveform's across both D8/D9, and IDK if they are conducting any amount or not.
My LTspice model of this has them only at pA.
Vaux does not have an output inductor, and is rated for 0.5A. Vstby does and is rated for 2A. Are they both the same type of converter? Or is Vaux without an OP inductor a Flyback winding ?? Both L2 and L3 are low when the primary is high. I thought a forward converter was conducting on the output, when the primary was. But IDK for sure what this is, or what A FC always does.
