Fine output voltage control of a phase-controlled converter

위상정류제어기의 정밀출력제어

Diode and thyristor-based bridge converter have been used for ac/dc conversion. Comparatively, diode bridges are simpler, more robust, less expensive and have a better power factor. However when voltage regulation is required, the thyristor-based phase-controlled converter have been used. But their use is limited by the low power factor and considerable harmonics in the input and output. An ac/dc power conversion scheme capable of fine output voltage control is investigated in this paper.
