摘要：
This paper presents a three-phase isolated soft-switching dc-dc converter suitable for high-power applications. Three-phase star-connected high-frequency transformers provide isolation between input and output. Primary-side of the converter consists of three-phase inverting bridge with reverse-blocking switches. Secondary-side consists of three-phase diode bridge followed by dc output capacitors, whose mid-point is connected to star-point of secondary. Leakage inductance of transformers and ac capacitors across secondary of each phase form LC resonant circuit facilitating smooth current commutation and zero-current switching. Detailed analysis of steady-state operation of converter is presented and validated with digital simulation and experimental results.
