摘要
A drive train comprising an electric machine including a rotor and a stator, the stator being electrically connected to an alternating grid and having a stator frequency, and a bidirectional system for converting an alternating current into another alternating current. The conversion system is connected between the grid and the rotor, and comprises an ac/dc converter connected to the network, and an inverter connected between the ac/dc converter and the rotor, the inverter and the rotor being interconnected at an intermediate point for each phase of the alternating voltage. The drive train comprises a band-stop filter for a target interval of between 0.6 times the stator frequency and 1.4 times the stator frequency, said band-stop filter being connected between the intermediate points and attenuating the voltage at the intermediate point for the frequencies of the target interval.
