  • Inverter for an electric machine, electric drive device for a motor vehicle and method for operating an inverter
    Patent number: 9899950
    Abstract: An inverter for an electric machine includes multiple phase systems, each including a high-side switching device and a low-side switching device, the high-side switching device being connected on one side to a first pole of an intermediate circuit and on another side to the low-side switching device, the low-side switching device being connected on one side to the high-side switching device and on the other side to a second pole of the intermediate circuit, the high-side switching device and the low-side switching device each having a circuit breaker which has a switching input, a power input and a power output, the power input and the power output being electrically connected with each other when the circuit breaker is closed and are electrically disconnected from each other when the circuit breaker is open. The inverter further has a control circuit and an intermediate circuit voltage limiting circuit.

  • Current distribution device for a high-voltage network and motor vehicle
    Patent number: 8827736
    Abstract: A current distribution device for a high-voltage network, in particular in a motor vehicle, includes at least two first connections that can be locked in such a way that, after a locking device is closed, a connector plugged into the connection can no longer be removed, wherein the first connections have a first locking plate as a common locking device.
