Abstract
A soft-switching bi-directional power converter includes a main inductor, a bi-directional switch module, a first switch module, a second switch module, and a control unit. The bi-directional switch module has a bi-directional switch and a resonance inductor. The first switch module has a first switch and a first resonance capacitor; the second switch module has a second switch and a second resonance capacitor. When the bi-directional switch is controlled to occur a resonance of the resonance inductor and the first and the second resonance capacitors so that a voltage of the first resonance capacitor drops to zero, the first switch is turned; when the bi-directional switch is controlled to occur a resonance thereof so that a voltage of the second resonance capacitor drops to zero, the second switch is turned on. Accordingly, the power converter can implement the bi-directional soft switching function.
