Abstract

An inverter includes a mains system side freewheeling pulse converter and a load-side freewheeling pulse converter, which are electrically connected on the DC side via a DC intermediate circuit. The mains system side and load-side freewheeling pulse converters each include switchable current valves in form of semiconductor switches that are made of silicon carbide with a high blocking voltage. The inverter can operate at higher voltages and frequencies, without affecting the load rating.
