Abstract
A power conversion circuit includes a bidirectional switch. The bidirectional switchhas a first gate terminal G, a second gate terminal G, a first ohmic terminal Sand a second ohmic terminal S. The bidirectional switchhas four operation states. In the first state, the bidirectional switchoperates as a diode having a cathode as the first ohmic terminal Sand an anode as the second ohmic terminal S. In a second state, the bidirectional switchoperates as a diode having an anode as the first ohmic terminal Sand a cathode as the second ohmic terminal S. In a third state, the bidirectional switchis bidirectionally conductive with via a diode between the first and second ohmic terminals Sand S. In a fourth state, the bidirectional switchcuts off a bidirectional current between the first and second ohmic terminals.
