The paper proposes a circuit for decreasing harmonic currents in the single phase rectifier. The circuit is a modified voltage tripler rectifier circuit which is composed of only passive devices such as capacitors, inductors and diodes. Accordingly the proposed circuit has the following merits;
1) High input power factor and small harmonic input currents,
2) High reliability and efficiency owing to the elimination of switching devices,
3) No switching noise generated by switching devices.
4) High capability for over load.
Using this circuit, 1200W (322V) dc power supply is constructed and the validity of the harmonic reduction is shown. The result fully satisfies the class-A restriction of harmonics.
