Isolated converters find wide application in SMPS, telecommunication, rectifiers etc. Among these topologies flyback converter is best opted for SMPS applications due to its simplicity in design, operation and less component count. High frequency dc-dc converters are subjected to high switching losses hence an auxiliary switch is designed to perform soft switching in main switch. The devices used in the converter are operated either in ZVS or ZCS to reduce the switching loss of the converter. This improves the converter performance. The converter designed is simulated, realized and presented in detailed for a laboratory model of 1.08W, 3.3V, 50 kHz.
