一种带飞跨电容的新型交错式三相单级PFC AC-DC变换器

A new interleaved three-phase PFC ac–dc single-stage multilevel is proposed in this paper. The proposed converter can operate with reduced input current ripple and peak switch currents due to its interleaved structure, a continuous output inductor current due to its three-level structure, and improved light-load efficiency as some of its switches can be turned ON softly. In the paper, the operatio...
