Patent ID: 6985371

Claim:
A choke arrangement for an output of an inverter, a phase output of the inverter being configured to be composed of two or more parallel branches, each of which comprises an upper (V 1 , V 3 , V 5 ) and a lower (V 2 , V 4 , V 6 ) 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, an output of each branch being composed of a point between the components, the arrangement comprising branch-specific single-phase chokes (L 1 , L 2 , L 3 ), first ends of which chokes are arranged to be coupled to the outputs of the power semiconductor components and second ends together to form the phase output of the inverter, characterized in that the single phase chokes are formed around a yokeless, columnar core ( 91 ; 101 ).
