Title:
RECTIFIER DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/005006
Kind Code:
A1
Abstract:
Disclosed is a rectifier device that is configured so as to follow a desired target current waveform by chopping a semiconductor switch and is provided with an AC-voltage phase detection means (201), an AC-current detection means, and a DC-voltage detection means. A DC voltage (Vdc*) is adjusted so as to make the phase (θON) at which the chopping of the semiconductor switch starts match a desired phase (θON*). In the first half of the cycle of an AC power source, the target current waveform is a combination of constant values or a monotonic increase, and the second half includes segments in which the target current waveform is zero. This makes it possible to reduce both harmonic currents and circuit loss and maintain the same current waveform even if the DC voltage detection precision is not high or there are load changes.
