A novel three-phase full-bridge power factor corrector is presented in this paper. The corrector operates in discontinuous conduction mode (DCM), the peak of input current follows the input voltage automatically. It can achieve zero-voltage-switching (ZVS) for the leading-leg switches and zero-current-switching (ZCS) for the lagging-leg switches without adding any auxiliary device. Due to the adoption...
This paper presents a three-phase single-stage active power factor correction (APFC) converter which is based on full-bridge structure and uses a simple circuit structure. It operates in discontinuous conduction mode (DCM), the peak of input current follows the input voltage automatically. The electrical isolation between input and output sides and output voltage regulation can be achieved as well...
