Abstract
A converter includes: a first transistor (Q) connected between a first output terminal (T) and an input terminal (T); a second transistor (Q) connected between the input terminal (T) and a second output terminal (T); first and second diodes (D, D) connected in anti-parallel to the first and second transistors (Q, Q), respectively; and a bidirectional switch that is connected between the input terminal (T) and a third output terminal (T) and that includes third and fourth transistors (Q, Q) and third and fourth diodes (D, D). The first and second diodes (D, D) and the third and fourth transistors (Q, Q) each are formed of a wide band gap semiconductor. The third and fourth diodes (D, D) and the first and second transistors (Q, Q) each are formed of a semiconductor other than the wide band gap semiconductor.
