More Information
Summary:A power module for a converter, in particular for a multilevel converter. The power module includes a link circuit capacitor, two connection terminals, at least one half-bridge connected in parallel with the link circuit capacitor and having two semiconductor switches, and, for each half-bridge, a bypass diode connected in parallel with a first semiconductor switch of the half-bridge and a load-relief circuit group connected in parallel with the first semiconductor switch. The load-relief circuit group has a load-relief thyristor and a load-relief diode connected in series with the load-relief thyristor.
