BIDIRECTIONAL SWITCH CIRCUIT AND POWER CONVERTER PROVIDED WITH SAME

摘要

A bidirectional switch circuit includes two switching elements (SW1, SW2) connected to conduct a current in both directions. The two switching elements (SW1, SW2) are connected in series to each other. Of the two switching elements (SW1, SW2), the switching element (SW1) to which a reverse voltage is applied, a voltage of a source (S1) of one of the switching elements (SW1, SW2) being higher than a voltage of a drain (D) of the one, is configured to conduct a current from the source (S1) to the drain (D) even when an on-drive signal is not being input to a gate terminal (G1) of the one.
