PURPOSE:To reduce an IHM distortion by turning ON and OFF a transistor which outputs a load of a capacitor by a timing signal of a timer, thereby producing a smoothed DC having less ripple. CONSTITUTION:An AC power is applied through a power source transformer 1 to rectifiers 2-4, and capacitors 5-7 are charged. The capacitors 5-7 are discharged by sequentially turning ON transistors 8-10 to output a smoothed current. The transistors 8-10 are shifted at 120 deg. by a timer 16, and sequentially turned ON. |
