摘要： This invention relates to a PWM power converter for switching a plurality of bridge-connected semiconductor switching elements (11 - 14) based on PWM signals. As the semiconductor switching elements (11 - 14), elements with a low ON voltage and small conduction loss, and elements with a small switching loss and capable of high-speed switching are combined to improve power conversion efficiency.
