Abstract

The foregoing describes a power converter apparatus (200) with at least a first power converter (101-1) and a second power converter (101-2) connected in parallel, so as to each receive an AC voltage generated by an electrical machine (104) and output a DC voltage on a DC bus (105P, 105N). Each of first and second power converters (101-1, 101-2) is coupled to respective first and second winding arrangements (102-1, 102-2) for receiving the AC voltages, and the first winding arrangement is grounded by a first impedance (201-1) and the second winding arrangement is grounded by a second impedance (201-2). The first impedance (201-1) has an effective impedance value which is different to that of the second impedance (202-1) such, in use, a zero-sequence current between the first and second power converters at least partly cancels a common-mode voltage component.
