An Interleaved Three-Phase PWM Single-Stage Resonant Rectifier with High-Frequency Isolation

This article proposes a novel interleaved three-phase pulsewidth modulation (PWM) single-stage resonant ac-dc converter with high-frequency isolation. The proposed converter comes from an interleaved three-phase power factor correction (PFC) semistage and a three-phase LLC resonant dc-dc semistage. Soft-switching commutation can be achieved on the power switches in this converter including zero-vo...
