Type 3 compensator for forward/buck converter
I am trying to build a isolated forward converter with voltage mode feedback. For some reason, I am unable to achieve required crossover frequency. To simplify everything, I have change the circuit to ...

Why are these transformer windings used connecting the switch and the series pass regulator in this circuit?
I am looking into this multi-output forward converter and cannot figure why these highlighted windings are connected to the switching side. There's already an inductor to handle the recovery reset. ...

Core demagnetisation - What is the condition?
Consider forward converter topology.
What is necessary for core to be successfully demagnetised? Does the magnetising current has to reach absolute zero amps, or even little negative is advantage?
How ...

Simple forward converter - strange demagnetisation
I am trying to build a simple forward converter. After MOSFET turns off I am demagnetising to 100 µF cap on secondary side. There is about 1 µs core doing nothing and after that demagnetisation starts ...

Supply of the primary side of the transformer in a forward, half-bridge converter
Why is it that in most forward, half-bridge converters, one of the transformer windings is connected with two capacitors (to VCC and GND):
when my simulations shows that one capacitor (that block DC ...

Peak-current mode control, active clamp forward converter: magnetization vs. reflected current
I figured out the forward converter, and I'm currently reading app-note where state:
The converter is a peak current-mode controller that controls the peak current as seen by the
current-sense ...

Why duty cycle can be greater than 50 in a forward converter with active clamp?
In a forward converter, the theoretical limit of the duty cycle is 0.5. This is necessary in order to have time to discharge the magnetizing inductance of the transformation. However, the duty cycle ...

Simulation Issues in Forward converter- Current Mode Design
I am trying to simulate the LT8310 part in LTspice. Based on my understanding, this part can operate in either the current mode or the duty mode. I am interested in the current mode design. The block ...
