A nondissipative snubber applied to the forward-PWM-ZVS-SR

This paper presents a forward converter with a nondissipative snubber. This approach allows the main switch to work in a ZVS way and the auxiliary switch to work in a ZCS way. Two capacitors, one inductor, one switch (auxiliary switch) and one diode in series with the main switch compose the nondissipative snubber.
