The forward converter is a DC/DC converter that uses a transformer to increase or decrease the output voltage (depending on the transformer ratio) and provide galvanic isolation for the load. For the active-clamp forward, the capacitor on the transformer generates a higher negative voltage, so that the demagnetization is achieved in a shorter time. The aim is to analyze the switching transients at, or close to, zero voltage across the semiconductor devices so as to achieve zero, or low, switching losses FORWARD.
