摘要： This invention relates to a PWM power converter for switching a plurality of bridge-connected semiconductor switching elements based on PWM signals. As the semiconductor switching elements, 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.
