To improve the current waveform of diode rectifiers, we propose a new operating principle for the voltage-doubler diode rectifiers. In the conventional voltage-doubler rectifier circuit, relatively large capacitors are used to boost the output voltage, while the proposed circuit uses smaller ones and a small reactor not to boost the output voltage but improve the input current waveform. A circuit design method is shown and confirmed experimentaly. The experimental results of a 1.6kW rectifier show that the proposed diode rectifier satisfies the harmonic guide lines. A high input power factor of 97% and an efficiency of 98% are also obtained. The new rectifier needs no controlled switches to meet the harmonic guide lines, resulting in a simple, reliable and low-cost ac-to-dc converters in comparison with the boost-type current-improving circuits.
