Title: BIDIRECTIONAL SWITCH CIRCUIT, ELECTRIC POWER CONVERTER EMPLOYING SAME, AND METHOD OF CONTROLLING SAME
Abstract:
[Problem] To provide a bidirectional switch capable of soft switching, while having a simple circuit configuration. [Solution] This bidirectional switch circuit is characterized by being provided with: two reverse-blocking type switching elements connected in anti-parallel; and one soft switching capacitor connected in parallel with the switching elements that are connected in anti-parallel. Alternatively, the bidirectional switch circuit is characterized by being provided with: two switching elements with flyback diodes, connected in anti-series; and one soft switching capacitor connected in parallel to the two ends of the switching elements that are connected in anti-series.
