。 In a controller that controls the opening degree of a pulse motor valve for controlling the flow rate of refrigerant in an air conditioner, etc., a chopper regulator is used as the power source for driving the pulse motor valve, and the chipper regulator is A first resistor, a second resistor, and a third resistor are connected in series to determine the output voltage, and the output voltage of the output terminal A of the voltage regulator is divided by these resistors. input the voltage to one input terminal B,
An output control circuit to which a reference power source is input to one input terminal C, a switching element connected in parallel to the second or third resistor, and a control signal generation for controlling ON/OFF of the switching element. By providing a circuit, when the pulse motor valve starts to open from a fully closed state, by turning on the switching element, the driving voltage of the pulse motor valve is made higher for a certain period of time than at other times. A power source for driving a pulse motor valve, which is characterized by:
