<P>PROBLEM TO BE SOLVED: To provide an improved power conversion system and method. <P>SOLUTION: A power conversion system (50) includes a power transformer (62) for receiving AC power at a first voltage from an input side (52) and for delivering AC power at a second voltage to an output side (56). The power conversion system also includes a power converter (60) which includes an input side converter (72) on the input side and an output side converter (74) on the output side which are coupled through a plurality of DC links (75). A converter controller (70) in the power converter provides control signals to the input side converter and the output side converter for regulating active power and reactive power flowing through the power converter. Each of the input side converters and the output side converters includes at least two power converter transformers (104, 88) coupling between respective power converter bridges (102, 76) coupled to the plurality of DC links and the input side or the output side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
