Component-Minimized Three-Phase Power Converters

12.1    SOLUTIONS FOR REDUCTION OF NUMBER OF COMPONENTS

Previous chapters have extensively analyzed the three-phase converter based on six power semiconductor switches. One of the major preoccupations for the use of this conventional topology within industrial products is related to cost reduction. It has been shown that the largest cost share corresponds to building the power stage.

Accordingly, one approach to cost reduction would rely on seeking new topologies with a reduced number of components. This is especially important for applications in the horsepower range up to several tens of kilowatts.

Different solutions have been reported in the literature during the last twenty years or ...
