    摘要: A vehicle includes a motor, an alternating current (AC) power bus, a power inverter module (PIM), and a controller. The PIM includes a semiconductor die assembly with semiconductor power switches arranged in electrical parallel for delivering AC power to the motor via the bus. The controller determines an operating mode of the vehicle, selects and activates a designated one of the switches during a threshold low-current state of the PIM, and selects and activates all of the switches during a high-current state of the PIM. A PIM assembly for the vehicle includes the die assembly and controller. A method for optimizing energy efficiency of the vehicle includes providing the die assembly noted above, automatically determining the operating mode, and selecting and activating one of the switches when the operating mode corresponds to the threshold low-current state, and all of the electrical switches during the threshold high-current state of the PIM.

    摘要: A vehicle includes an energy storage system (ESS) rechargeable using electrical power from an off-board AC power supply, a traction power inverter module (TPIM), one or two motors, and a controller. The TPIM has two inverters. The controller energizes designated semiconductor switches of the TPIM and designated induction coils of the motor to boost electrical power from the AC power supply for charging the ESS when the vehicle is not running. With two motors, a contactor allows induction coils of a first motor to be connected to the switches of the first inverter as an input filter, and an additional semiconductor switch is positioned between the ESS and an output side of the switches of the second inverter. A controller charges the ESS by energizing designated semiconductor switches of the TPIM and induction coils of the motor to charge the ESS without using an onboard battery charger module.

    摘要: A method of detecting a phase winding fault in a multi-phase electric machine is executable via a motor controller, and includes measuring feedback signals of the machine, including each phase current, and generating reference phase voltages for each phase. The method includes calculating a predetermined voltage value using the feedback signals and reference phase voltages, and comparing the voltage value to a corresponding threshold to determine the fault. A control action is executed when the voltage value exceeds the corresponding threshold. The voltage value is one or more of: a ratio of a normalized negative sequence voltage to a modulation index, an RMS voltage for each phase, and total harmonic distortion of each phase current. An apparatus detects the fault, and includes a motor controller and an algorithm as set forth above. The apparatus may include a voltage inverter for generating a multi-phase alternating current output for powering the machine.

    摘要: Methods and systems are provided for detecting loss of isolation of a motor, connections, or phase cables while an AC motor is operating. The system includes a power supply that is substantially isolated from the ground or chassis having a power supply voltage, and a power inverter electrically coupled to the power supply. The power inverter is configured to provide AC current from the power supply in an AC phase at an AC terminal, with the phase having current at a fundamental frequency that controls the motor speed. An electric motor is electrically coupled to the AC terminal of the power inverter and has a chassis that is substantially electrically isolated from the AC terminal of the power inverter under normal operating conditions. A processor is configured to control the AC current provided by the power inverter. The processor is configured to receive a first voltage signal related to current flowing through a motor chassis. The first voltage signal includes a first component related to the fundamental frequency of the phases, and a second component related to the power supply voltage. The processor is further configured to filter the first voltage signal to attenuate the second component, to measure an amplitude of the first component, and to determine if an AC loss of isolation condition exists by comparing the amplitude of the first component to a fault value.
