回路。A switching circuit is driven by the pulse train generated by the pulse width control circuit to switch the current from the DC power supply, and the current is sent to the YIG element driving electromagnet via a rectifier circuit consisting of a rectifier diode and a smoothing capacitor. In the circuit that supplies the drive current, a resistor is inserted in series with the electromagnet, and the resistor sends both a signal detected by the current flowing through the electromagnet and a control signal supplied from the outside to the pulse width control circuit. An electromagnet driving circuit characterized in that the <j pulse width control circuit generates a pulse number having a duty ratio inversely proportional to the voltage difference between the two signals.
