  • Voltage converter, electric drive system and method for reducing interference voltages
    Patent number: 10910944
    Abstract: The present invention relates to interference suppression of interference signals from 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.
    Type: Grant
    Filed: June 17, 2016
    Date of Patent: February 2, 2021
    Assignee: Robert Bosch GmbH
    Inventors: Dennis Burger, Eckart Hoene, Martin Lauersdorf, Norbert Schneider, Roland Eidher
