A voltage drop compensator that supplies alternating current compensated for the rated voltage, comprising: a semiconductor switch for a bypass power supply path that directly connects the load to the alternating current power source; a detection circuit that detects a voltage drop in the alternating current power source; A power supply line that closes the semiconductor switch to hold the inverter in a drive stop state when the voltage of the AC power source is normal based on the detection output, and opens the semiconductor switch to release the drive stop state when the voltage of the AC power source drops. A voltage drop compensator comprising a switching circuit and.
