Boost converter having reduced output voltage and method of operation thereof

摘要

For use with a boost converter (100) having a three phase rectifier (130), a boost switch (140) coupled across the rectifier and a boost diode (145), operable in discontinuous mode, coupled between the rectifier and an output of the boost converter, a circuit for, and method of, providing a reduced output voltage from the boost converter. In one embodiment, the circuit includes an autotransformer (155), coupled across the output, that has an intermediate tap for providing the reduced output voltage. <IMAGE>
