In this paper, a new hybrid resonant bridgeless ac-dc PFC boost converter operating in continuous-conduction-mode (CCM) is proposed for neighborhood electric vehicle (NEV) battery charging. This hybrid-resonant boost converter has two active switches that operate in pulse-width modulation (PWM) and hybrid-resonant modes of operation. This combined modulation technique is called hybrid resonant PWM (HRPWM). The proposed converter with HRPWM features several benefits. The gates of the two active switches are tied together, so, the converter does not need any extra circuitry to sense the positive, or negative line-cycle operation. The semiconductor devices operate with a voltage stress close to the output voltage. The resonant tank components are relatively small in size and the hybrid-resonant mode of operation alleviates the reverse recovery losses for the body diode. The converter architecture exhibits less common mode noise compared with the dual-boost and bridgeless boost converters. Moreover, the converter architecture enables simple implementation of lightning and surge protection systems. And it has inherent inrush current limit capability. Experimental results of a prototype unit converting a universal ac input to a 400 V dc output at 650 W and 70 kHz switching frequency are presented to verify the proof of concept.
