ABSTRACT:
An integrated three-phase power converter and method of operation thereof is provided. The integrated three-phase power converter includes: (1) first and second power switches coupled between corresponding rails of said power converter, (2) an input stage, including first, second and third L-C branches coupled between said first, second and third phase inputs and a node between said first and second power switches, adapted to receive phase voltages from a source of electrical power, and (3) an output stage, coupled to said first and second power switches, that provides a DC output voltage at said output, said first and second power switches cooperating to employ said input stage to reduce input current total harmonic distortion (THD) on all three of said phase inputs and said output stage to convert said phase voltages to said DC output voltage.
