Title:
RECTIFIER CIRCUIT DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/008139
Kind Code:
A1
Abstract:
This invention provides a rectifier circuit device that achieves both the reduction of power supply harmonic waves and the reduction of circuit loss at the same time. There are included an AC voltage phase detecting means (201), an AC current detecting means (103) and a DC voltage detecting means (110). It is arranged that a semiconductor switch (104) be chopped to follow a desired current waveform. The DC voltage is adjusted to cause a phase, in which to halt the chopping, to become a desired phase, while, if a phase width for which to continue the chopping exhibits a value less than a set value, the DC voltage is adjusted, on a priority basis, to cause the phase width, for which to continue the chopping, to exhibit the set value. As a result, the target current waveform exhibits a combination of a monotonous increase and a constant value during the former half of the half period of the AC power supply and includes a section exhibiting a zero value during the latter half thereof.
