Abstract
A two-wire AC switch suppressing heat from a bidirectional switch element inside the switch is provided. The two-wire AC switchconnected between an AC power supplyand a loadincludes: a bidirectional switch elementwhich flows passing current bi-directionally, selects whether to flow or block the current, is connected in series with the AC power supplyand the loadto form a closed-loop circuit, and is made of a group-III nitride semiconductor; a full-wave rectifierperforming full-wave rectification on power supplied from the AC power supply; a power supply circuitsmoothing a voltage after the full-wave rectification to generate DC power; a first gate drive circuitand a second gate drive circuiteach outputting a control signal to the bidirectional switch element; and a control circuitcontrolling the first and second gate drive circuitsand
