When the voltage is V, the full-wave rectifier circuit is used.
When the voltage is V, the reflux type half-wave rectifier circuit is connected. When the voltage value of the AC power supply is 400 V, the reflux type half-wave rectifier circuit is connected to a resistor having a predetermined resistance value, and the voltage between the terminals of the electromagnetic magnet is connected.
