Abstract
PURPOSE:To reduce a harmonic current by parallel connecting two-stage cascade connected inverters to the DC output side of first diode rectifiers and by providing three-phase AC switches and second diode rectifiers. CONSTITUTION:The AC ends of three-phase bridge connected first diode rectifiers 10 of a power converter are connected to a three-phase AC power and inverters 5 are connected the DC ends of said diode rectifiers via reactors 2. The output of said inverters is prallel connected in a common homopolarity manner via insulating transformers 6 and second diode rectifiers 7 and connected a capacitor 8. Also, three-phase AC switches 20 are connected between the interconnecting point of said inverters 5 and the three-phase AC power. Thus, said three-phase AC power is rectified into three-phase half-wave rectification waveforms and controlled it waveform by both inverters 5P-5N divided into positive and negative groups, respectively. Then, the DC current difference of said first diode rectifiers 10 is controlled via the three-phase AC switches 20 to flow to the AC power.
