POWER CONVERTER AND METHOD FOR OPERATING A POWER CONVERTER

摘要

The invention relates to a pulse-controlled inverter comprising one or more semiconductor switches and freewheeling diodes arranged in parallel to each semiconductor switch. The semiconductor switches are triggered only when the current does not flow through a freewheeling diode that is arranged in parallel to the semiconductor switch. This allows the number of triggering processes for the semiconductor switch to be reduced. The reduced number of triggering processes for the semiconductor switches results in lower power losses and an increased service life of the entire system.
