Abstract:
A choke arrangement and a method in conjunction with an inverter, the phase output of the inverter being configured to be composed of two or more parallel branches, each of which comprises an upper (V1, V3, V5) and a lower (V2, V4, V6) power semiconductor component at the output, the upper one of which being coupled to a positive voltage of a direct voltage intermediate circuit and the lower to a negative voltage, the components being in series, the output of each branch being composed of a point between the components. The arrangement comprises branch-specific single-phase chokes (L1, L2, L3), the first ends of which chokes are arranged to be coupled to the outputs of the power semiconductor components and the second ends together to form the phase output of the inverter.
