交流駆動回路。In an AC drive circuit for a relay that uses AC power to energize a relay that changes the switching mode of the relay switch only when the relay coil is energized, the AC power is rectified by a full-wave rectifier circuit, the rectified output is stabilized by a constant voltage circuit, The output from the constant voltage circuit is applied to a series circuit consisting of a relay coil and a transistor, and the output from the constant voltage circuit is applied to the base of the transistor through a parallel circuit of a capacitor and a resistor, and the impedance of the transistor is The resistance value of the resistor is small while the capacitor is being charged, and the impedance of the transistor is large so that a small excitation current necessary to maintain the switching mode of the relay flows through the relay coil after the capacitor has finished charging. An alternating current drive circuit for a relay, characterized in that the value is selected to be
