Isolated DC-DC Converters: Single-Ended Forward Converter

In this video, we look at the Single-Ended Forward Converter, which is essentially an isolated version of the Buck Converter. We introduce the topology and provide the motivation for an additional clamp circuit to ensure that the converter functions properly. Then, the converter is analyzed, and the switching waveforms are developed.

Hello Sandeep, thanks for the clear explaination. May I know what value (or value range) of Lu should be considered in practical design? It looks like there is no constrain in choosing Lu and hence iu. Will smaller iu be favourable to less power loss?

Hello Sandeep Sir, In the potential clamp circuit section the circuit which is the combination of diode, capacitor, and resistor is also called the snubber circuit. Is it right? Does it have the same function as the snubber circuit?
