。 A failure detection circuit is connected to each inverter in a device that compensates for the instantaneous voltage drop in the power supply voltage by applying energy stored in a capacitor as a voltage in series from the inverter to the power supply for the load via an injection transformer when the power supply voltage drops instantaneously. A series instantaneous voltage drop compensator is characterized in that, when an inverter fails, only the failed inverter device is disconnected from the circuit, and furthermore, a bypass switch connected to the secondary side of the injection transformer is turned on for operation.
