This paper investigates a series LC resonance based current-fed DC-DC converter to enable wide-range zero voltage switching (ZVS) of the semiconductor devices for high-voltage gain applications. A series resonant tank allows natural commutation of the semiconductor devices and improved transformer utilization owing to the sinusoidal current through the transformer primary by operating the converter near the resonant frequency of the LC tank. ZVS of the active devices minimizes the switching losses, duty cycle loss and also limits the peak and circulating current allowing the use of lower rated components. Furthermore, proposed converter employs a simple duty cycle control with an interleaved boost derived structure and voltage-doubler to meet the desired output voltage levels. The operational principles, detailed mathematical analysis and simulation results are presented to verify the feasibility of the proposed idea.
