What's the end goal?
Vin=?
Vout=?
Iout=?
Galvanic isolated:
Vin1: 60V
Vin2: 60V
Vin3: 160V
Vin4: 160V
Vin5...X: 12V Low current Driver Supplies (Just a small toroid, 1 Diode, 1 Cap and that's all. Not much for that at all!)
Output - Always referenced to ground, Amps as max RMS rating:
Vout: 36V+ 6A
Vout: 36V- 6A
Vout: 130V+ 5A
Vout: 130V- 5A
Vout: 12V+ 1A
Supply for a Home Reciever. The supply is about 100 times more difficult, than the Amplifier section. That power classes...
Also, I want to rund Buck mode for lower Currents through the inductors. That's, why I don't use 30V or so, to Boost them up. no, I want to buck it down.
So you would recomment PNP Transistors? Well, maybe you aren't that wrong, actually...
Still need a way, to drive this.

I was trying to use Photocouplers. That worked at the beginning. But the Current amplification failed at 2 things:
Higher Frequency was lower amplitude on output. 60-70kHz is my goal.
Higher or lower currents to swich also killed the signal. Could you make me a simple circuit for connecting the 2 sides of the circuit example in the attachment?
It just shows the basic idea of my converter. There was an NMOS - Ignore it an think of, if there was simply a PNP Transistor instead.
I'd love to have a circuit for that, because I fail for hours now.
