Beschreibung
Zusammenfassung:	The invention discloses a voltage converter, an electric drive system and a method for reducing interference voltages. The present invention relates to interference suppression of interference signalsfrom an inverter. To this end, a current-compensated inductor is provided at the input end of an inverter, in particular a pulse-controlled inverter. This current-compensated inductor is preferably arranged between a DC voltage source and an intermediate circuit capacitor of the inverter. Polyphase inductors at the AC voltage output of the inverter can be dispensed with in this way. 本发明涉及从逆变器中消除干扰信号。为此在逆变器、尤其脉冲逆变器上在输入端设有电流补偿的扼流圈。这个电流补偿的扼流圈最好布置在逆变器的直流电压源与中间回路电容器之间。通过这种方式可以省去在逆变器的交流电压输出上的多相扼流圈。
