Einrichtung zur Begrenzung der Änderungsgeschwindigkeit der Ausgangsgrössen eines über einen Gleichspannungszwischenkreis selbstgeführten Umrichters
摘要
The device uses a low pass LC filter inserted between each of the outputs (3) of the drive regulator and the respective drive motor connections. The filter has a resistor in parallel with the inductance and is connected in series with a current-compensating choke coil (L1). Pref. the capacitors of the low pass filters are connected in a Y or delta configuration. Each capacitor may be provided by 2 series capacitors (C) with the junction between them coupled to a respective line between the choke coil combination and the motor connection. <IMAGE>
