A snubberless current-fed push-pull dc/dc voltage doubler is proposed with zero voltage switching (ZVS) turn-on of low voltage current-fed devices by using the parasitic resonance between the drain-source capacitance of MOSFETs and the leakage inductance of the high frequency transformer. Secondary modulation helps reduce switching losses further by obtaining zero current switching (ZCS) turn-off...
This paper presents high-frequency current-fed fuel-cell inverter for residential loads. The front-end high-frequency current-fed dc/dc converter presents zero-voltage switching (ZVS) of all switches for wide variation in fuel cell stack voltage and output power. Rectifier diodes undergo zero-current switching. It results in increased efficiency of the system. Load-connected inverter is operated using...
This paper proposes an improved current-fed zero-voltage switching isolated boost converter suitable for fuel cell applications. Preserving the inherent advantages of the current-fed converter which include smaller input current ripple, lower diode voltage rating, and lower transformer turns ratio, the proposed converter does not require any clamping and start-up circuits unlike the conventional current-fed...
