Title:
INVERTER CIRCUIT FOR AN ELECTRIC DRIVE, ELECTRIC VEHICLE WITH AN INVERTER CIRCUIT AND METHOD FOR OPERATING AN INVERTER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/072096
Kind Code:
A3
Abstract:
The invention relates to an inverter circuit (2) for controlling an electric drive (3) with improved suppression of interference signals. The use of at least two notch filters (21, 22) allows the reliable suppression of occurring interference signals. At the same time, it is possible to significantly increase the switching frequency of the inverter (20) without any disadvantageous effects on the occurring interfering pulses. The invention further relates to an electric vehicle (5) which is equipped with said inverter circuit (2).
