Abstract :
To improve the current waveform of rectifiers, we propose a new operating principle for the voltage-doubler rectifiers with 200 V utility voltage. For the limited input range, 0.3 kW~1.6 kW, the conventional diode voltage-doubler rectifier can be designed such that the input current satisfies the harmonic guidelines. A high power factor of 97% and efficiency of 98% are experimentally obtained. The proposed method seems to be very attractive for an air conditioner DC source using inexpensive and reliable components
