Zero current switching current-fed parallel resonant push-pull (CFPRPP) converter

Current-fed parallel resonant push-pull (CFPRPP) converter has been analyzed and designed. The topology maintains zero current switching (ZCS) of the semiconductor devices. Variable frequency modulation has been adopted for load voltage regulation and to achieve ZCS over wide input voltage variation. Soft switching permits to raise the device switching frequency resulting in compact and light converter. At fixed input voltage, ZCS and load voltage are load independent. Natural clamping of devices by ZCS is achieved using parallel resonance. Pushpull converters have only two devices with common ground with source requiring simple gate drive circuitry. A comprehensive study of the proposed converter including steady-state analysis and design has been performed. Also, a 500 W prototype was developed in the laboratory to evaluate the performance of the converter. Experimental results have been demonstrated to verify the claims.
