    摘要： Systems and methods are provided for monitoring current in an electric motor. An electrical system includes a (DC) interface, an electric motor, an inverter module coupled between the DC interface and the electric motor, a first current sensor between a first phase leg of the inverter module and a first phase of the electric motor to measure a first current flowing through the first phase of the electric motor, a second current sensor between the first phase leg and the DC interface to measure a second current flowing through the first phase leg, and a control module coupled to the first current sensor and the second current sensor. The control module is configured to initiate remedial action based at least in part on a difference between the first current measured by the first current sensor and the second current measured by the second current sensor.

    摘要： A reverse polarity protected system comprises a voltage source that includes positive and negative terminals. A polarity-sensitive device has a first terminal that communicates with the positive terminal of the voltage source, and that includes a second terminal. A low-resistance switch communicates with the first and second terminals of the voltage source, and communicates with the second terminal of the polarity-sensitive device. The low-resistance switch assumes a conducting state between the second terminal of the polarity-sensitive device and the negative terminal of the voltage source when a first voltage at the positive terminal of the voltage source minus a second voltage at the negative terminal of the voltage source is greater than a threshold voltage. Otherwise, the low-resistance switch assumes a non-conducting state.

    摘要： In order to provide a modular arrangement, an inverter for an electric traction motor used to drive an automotive vehicle is positioned in proximity with the traction motor. The inverter is located within a compartment adjacent to one end of the electric traction motor and is cooled in a closed system by spraying a liquid coolant directly onto the inverter. The liquid coolant absorbs heat from the inverter and is cooled by a heat exchange arrangement comprising a reservoir with pipes carrying a second coolant from the radiator of the automotive vehicle. In a preferred embodiment, the coolant is collected from the inverter in an annular reservoir that is integral with the compartment containing the inverter. In accordance with one embodiment of the cooling arrangement, heat from the inverter vaporizes the liquid coolant by absorbing heat from the inverter during a phase change from a liquid to a vapor. The vaporized coolant is condensed by a circulating second coolant in pipes connected to the vehicle's radiator through a condenser that is preferably coaxial with the motor and the annular reservoir, which annular reservoir in the second embodiment collects overspray liquid coolant. In order to avoid degrading the inverter, the coolant is a dielectric fluid.
