Abstract

[PROBLEMS] Manufacture of a high speed switch used in an instantaneous voltage drop compensator become difficult economically because technical difficulty increases as the circuit voltage increases. [MEANS FOR SOLVING PROBLEMS] A first series transformer is connected between an AC power supply and a load. A high speed switch and a second series transformer are connected in parallel to the primary of the first series transformer, and the output side of an inverter is connected to the primary of the second series transformer. Upon occurrence of instantaneous voltage drop, a voltage generated from the inverter is superimposed on the power supply voltage through the second series transformer and the first series transformer.
