タ装置。[Claims for Utility Model Registration] (1) A rectifier that converts alternating current into direct current, a capacitor that is charged by the direct current output of the rectifier, and a current-limiting resistor that is inserted in series between the rectifier and the capacitor to suppress the charging current. an electromagnetic switch having a contact that short-circuits the current limiting resistor after charging is completed; an inverter that converts the DC voltage charged in the capacitor to AC voltage; a control power source that receives the DC voltage and outputs control power. In the device provided with the circuit, the current limiting resistor is configured with a series circuit of a first current limiting resistor and a second current limiting resistor, and the input power source of the control power supply circuit is connected to the first current limiting resistor. An inverter device characterized in that the inverter is configured to be connected from a connection point between the current limiting resistor and the second current limiting resistor and one end of the capacitor. (2) The resistance values of the first current limiting resistor and the second current limiting resistor are based on the minimum operating input voltage of the control power supply circuit, the maximum allowable input voltage when applying the input voltage in a stepwise manner, and the inverter. The inverter device according to claim 1, wherein the inverter device is determined based on the rated current of the switching elements constituting the inverter device.
