動回路。 An OR circuit that logically ORs and outputs pulse command signals that control stepping motors that drive waveguide switches used in artificial satellites, etc., and a differential circuit that outputs differential pulses from the output pulses of the OR circuit. a power supply circuit that starts outputting the power supply voltage supplied from the outside in response to the differential pulse; a delay time generation circuit that outputs a delay pulse after a predetermined time after the power supply voltage is output; and the delay pulse. and a cut-off circuit that cuts off the power supply voltage that is continuously output from the power supply circuit, and allows a primary current to flow through the stepping motor only during a period when the power supply voltage is being outputted. Wave tube switch drive circuit.
