Abstract Abstract: In this paper, a modified flyback snubber circuit for isolated bidirectional DC-DC converter has been introduced. The soft switching isolated snubber circuit provides an alternative path for the current difference created due to source inductance and leakage inductance. The auxiliary snubber circuit operates during the step-up conversion, and it only persists of the two semiconductor switch, two inductors one diode and two capacitors. Both semiconductor devices (G1, G2) of flyback snubber circuit achieve soft switching during turn ON and turn OFF condition. The PWM technique has been used to control the semiconductor devices. The different mode of operation has been discussed in detail. The effective performance of proposed converter system has been validated with the PSIM simulation tool. The proposed converter is compared with the active clamp converter based on efficiency. The loss comparison proves that flyback snubber circuit has high efficiency compared to active clamp converter.
