abstract
A converter output filter for an induction drive system is provided. The converter output filter (40) comprises an L-R-C network (41) that can be coupled between each converter output (38a, 38b, and 38c) of a converter (16b) and a DC-link midpoint node (35) of the converter (16b). Each L-R-C network (41) comprises an inductive element (42a, 42b, and 42c), a resistive element (44a, 44b, and 44c), and a capacitive element (46a, 46b, and 46c) coupled in series. An electrical device (18) can be coupled to the L-R-C network (41) between the respective inductive element (42a, 42b, and 42c) and the respective resistive element (44a, 44b, and 44c).
