A polyphase. converter circuit having p >= 3 phases (R Y, B) and a converter circuit element (1) provided for each phase (R, Y, B) is specified, each converter circuit element (1) having a rectifier unit (2) a DC , voltage circuit (3) which is connected to the rectifier unit (2) and an inverter unit (4) which is connected to the DC voltage circuit (4). In addition a first AC , voltage output (5) of each inverter unit (4) forms a phase connection (6), and second AC voltage outputs (12) of the inverter units (5) are star-connected. In order to produce harmonics which are as low as possible with respect to the fundamental of the voltage and the current of an electrical AC voltage …
