Abstract
An electrical inverter 18 for transforming an DC current into an AC current comprises at least one half-bridge 54. The half bridge 54 comprises at least two series connected semiconductor switches 58a, 58b, 58c, 58d inter-connecting an input terminal 54, 56 with an output terminal 50 of the inverter 18. A snubber capacitor 62a, 62b is connected in parallel to at least two semiconductor switches 58a, 58b, 58c, 58d of the half bridge 54.
