MAGNETIC AMPLIFIER AC/DC CONVERTER WITH PRIMARY SIDE REGULATION

摘要

In accordance with the present invention there is provided a single stage ac/dc converter operative to convert a universal ac input voltage to a prescribed dc voltage. The converter comprises a primary side in electrical communication with the input voltage. The primary side has a bridge rectifier and at least one switching device operative to selectively control an input current waveform. In this regard, the voltage is regulated on a dc storage bus of the primary side. In electrical communication with the primary side is a secondary side which has a variable reactor that is operative to selectively control a conduction period thereof. In this respect, the converter is operative to selectively generate the prescribed output voltage by independently controlling the input waveform on the primary side and controlling the conduction period on the secondary side.
