    摘要: A power line quality conditioning system for a vehicle includes an onboard rechargeable direct current (DC) energy storage system and an onboard electrical system coupled to the energy storage system. The energy storage system provides DC energy to drive an electric traction motor of the vehicle. The electrical system operates in a charging mode such that alternating current (AC) energy from a power grid external to the vehicle is converted to DC energy to charge the DC energy storage system. The electrical system also operates in a vehicle-to-grid power conditioning mode such that DC energy from the DC energy storage system is converted to AC energy to condition an AC voltage of the power grid.

    摘要: Systems and methods are provided for detecting a resonance on a bus coupled to an inverter module. A method involves generating a first signal on the bus with a first frequency and sweeping the first signal from the first frequency to a second frequency. A second signal, which may be influenced by a characteristic of a component coupled to the bus, is obtained from the bus during the sweep of the first signal from the first frequency to the second frequency. The method further involves determining a resonant frequency based on the first signal and the second signal and updating the inverter module such that the resonant frequency is not used as a switching frequency for the inverter module.

    摘要: A system and method of discharging a bus capacitor of a bidirectional matrix converter of a vehicle are presented here. The method begins by electrically shorting the AC interface of the converter after an AC energy source is disconnected from the AC interface. The method continues by arranging a plurality of switching elements of a second energy conversion module into a discharge configuration to establish an electrical current path from a first terminal of an isolation module, through an inductive element, and to a second terminal of the isolation module. The method also modulates a plurality of switching elements of a first energy conversion module, while maintaining the discharge configuration of the second energy conversion module, to at least partially discharge a DC bus capacitor.
