基于双移相调制策略的宽范围软开关高效率高频链逆变器分析与设计

A wide-range soft-switching high-efficiency cycloconverter-type high-frequency-link inverter with dual-phase-shift modulation strategy is proposed in this paper. By adding an auxiliary inductor in primary-side full bridge circuit and adopting center-tapped four-winding transformer structure, the soft-switching range for primary-side switches has been extended. The secondary-side active clamper net...
