This paper proposes a high power facter rectifier composed of only passive devices. It consists of a single phase diode rectifier having a L-C resonant circuit in parallel with the diode output and a series reactor to pumping up the charge stored in the resonant circuit capacitor. It enables wide current conduction width and decreases its peak value. As a result, harmonics in the input current is decreased and the power factor is improved, which will be satisfied the harmonic regulation enforced in near future.
The absence of switching devices as FETs makes high reliability, high efficiency, strength to over load, and no radio noise. In this paper, it is shown input harmonic current components, output voltage, and other characteristics by charts for circuit design. Input power factor of 98.4%, the total harmonic distortion of 17.4%, and the efficiency of 93.3% are confirmed by experiment with rated condition of 1.0kW, 100V system.
