ABSTRACT:
The electric power converter includes a series converter connected in series between an AC power supply1and a load6,and having capacitors30, 31as a power supply for the converter, switching devices12, 13, and diodes16, 17; and a parallel converter connected in parallel to the AC power supply1and having the capacitors30, 31, switching devices10, 11,and diodes14, 15. The series converter compensate the change in the voltage of the AC power supply1to feed a certain voltage to the load6, and the parallel converter conducts charging and discharging operations to compensate the changes in the voltages of the capacitors30and31caused by the compensating operations of the series converter. The converter suppresses the change of the AC power supply voltage and feeds a certain voltage to the load at a high efficiency and low running costs.
