Abstract:
1. A power control apparatus for supplying power between an electric machine and an energy source, said power control apparatus containing at least two converters comprising a plurality of switches, at least some of which switches belong to a set of switch modules comprising a plurality of switches, wherein at least one of the converters contains switches belonging to at least two modules and the switches of at least one module belong to two or more converters, wherein the power control apparatus comprises a three-phase mains inverter and a three-phase load-side inverter, which have a common direct-voltage intermediate circuit and which comprise three switch modules in all, each switch module consisting of three bidirectional switches and that the three-phase mains inverter contains three bidirectional switches one for each phase, each one of said bidirectional switches being placed in a different switch module, and that the three-phase load-side inverter contains six bidirectional switches in all, two parallel-connected bidirectional switches for each phase in each switch module.
