一种用于电动汽车应用中单相准Z源集成充电器的软开关调制策略

A modulation for a single-phase quasi-Z-source-integrated electric vehicle charger (qZSC) system is proposed, which can achieve multiple zero-voltage-switching and zero-current-switching (ZCS) transitions without any auxiliary circuit. Though the modulation has a couple of hard-switching turn-off transitions, they occur at low current values. The switch of a quasi-Z-source network also can be turn...
