Abstract : Zero-current (ZC) switching pulse-width modulated (PWM) fly back DC-DC converter is an extended version of the single switch fly back converter with an auxiliary circuit. The main switch and auxiliary switch operate at ZCS turn-on and turn-off conditions, and all uncontrolled devices in the converter operate at zero-voltageswitching (ZVS) turn-on and turn-off. Soft switching techniques are used in PWM DC-DC converters to reduce switching losses and electromagnetic interference (EMI). The circulating current for the soft switching flows only through the auxiliary circuit, the conduction loss and current stress of the main switch are minimized. The general principle of operation of ZCS flyback converter, its merits and demerits, simulink model and results has been summarized.
