METHOD FOR OPERATING A CONVERTER CIRCUIT

摘要

A method is disclosed for operating a converter circuit, in which controllable power semiconductor switches of the rectifier unit of a converter circuit are controlled by a rectifier switch signal and the controllable power semiconductor switches of the inverter unit of the converter circuit are controlled by an inverter switch signal. In order to reduce losses in the no-load state of the converter circuit, the rectifier switch signal is blocked in order to disconnect the controllable power semiconductor switches of the rectifier unit if defined conditions of the converter circuit are fulfilled.
