  • Inverter system controller power optimization
    Patent number: 10369887
    Abstract: An inverter for a vehicle includes a power controller and gate drive board (GDB) electrically in series, the controller including logic circuitry configured to, responsive to presence of an ignition signal, permit flow of low voltage power through the controller to the GDB to activate the GDB, and responsive to presence of a wake-up signal, but not the ignition signal, prevent flow of low voltage power through the controller to the GDB.
    Type: Grant

  • SHORT DETECTION AND PREVENTION FOR INVERTER SENSOR INPUTS
    Publication number: 20180138694
    Abstract: A vehicle may include an inverter including a tristate buffer. The vehicle may further include a short detection circuit connected to the inverter configured to output an inhibit signal indicative of abnormal electrical behavior to the tristate buffer such that inverter output is disabled. The short detection circuit may out the inhibit signal in response to a high value comparator signal indicating deviation from a high voltage threshold or a low value comparator signal indicating deviation from a ground voltage.
