レータ。 In a switching regulator equipped with an inverter section, the inverter section is divided into two systems: a main inverter circuit with a fuse connected to a transistor, and a backup inverter circuit with a fuse connected to a transistor. The present invention is characterized by comprising a switching switch for switching to the inverter circuit, an alarm contact for detecting fuse breakage in the main inverter circuit, and an electromagnetic switch that activates the changeover switch when the alarm contact detects fuse breakage. Switching regulator.
