  • OVERVOLTAGE PROTECTION FOR A CONVERTER
    Publication number: 20100134057
    Abstract: The invention relates to a method for protecting against over voltage that is simple to produce, economical, compact and is simultaneously effective against over voltage for a converter (8) provided for supplying an electric motor (1) comprising at least one motor phase (L1, L2, L3). Said converter comprises an electric intermediate circuit (10) and several half-bridges (13a, 13b, 13c) that are connected in parallel in the intermediate circuit and respectively comprise a circuit breaker (15a, 15b, 15c) on the high potential side and a circuit breaker (17a, 17b, 17c) on the low potential side, in addition to an intermediately connected phase connection (14a, 14b, 14c).

  • Inverter with a line-side and load-side freewheeling pulse converter using SiC switching elements
    Patent number: 6850424
    Abstract: An inverter includes a mains system side freewheeling pulse converter and a load-side freewheeling pulse converter, which are electrically connected on the DC side via a DC intermediate circuit. The mains system side and load-side freewheeling pulse converters each include switchable current valves in form of semiconductor switches that are made of silicon carbide with a high blocking voltage. The inverter can operate at higher voltages and frequencies, without affecting the load rating.
