  • Power supply topology for a multi-processor controller in an electric traction system
    Patent number: 8040092
    Abstract: A multi-processor controller is provided. The multi-processor controller can be used to control the operation of an inverter in a vehicle-based electric traction system. The multi-processor controller includes a first processor device having a first supply voltage node, a second processor device having a second supply voltage node, a first voltage regulator, and a second voltage regulator. The first voltage regulator has a first output voltage node coupled to the first supply voltage node, and the first voltage regulator is configured to generate a first regulated supply voltage for the first processor device. The second voltage regulator has a second output voltage node coupled to the second supply voltage node, and the second voltage regulator is configured to generate a second regulated supply voltage for the second processor device.

  • Control module for dynamic operation of a power inverter using an application specific integrated circuit
    Patent number: 7999503
    Abstract: Systems and apparatus are provided for a control module for operating an inverter in a vehicle. A control module comprises a first circuit card assembly and a microprocessor mounted on the first circuit card assembly. The microprocessor is configured to determine a phase modulation command for a first motor phase and determine a modulation criterion for the inverter. An integrated circuit is communicatively coupled to the microprocessor. The integrated circuit is configured to generate a first modulation signal based on the phase modulation command and the modulation criterion and generate a second modulation signal based on the phase modulation command and the modulation criterion.

  • MULTI-PROCESSOR CONTROLLER FOR AN INVERTER IN AN ELECTRIC TRACTION SYSTEM FOR A VEHICLE
    Publication number: 20100088441
    Abstract: A multi-processor controller is provided. The multi-processor controller can be used to control the operation of an inverter in a vehicle-based electric traction system. The multi-processor controller includes a master processor device having three serial peripheral interfaces (SPIs), and three slave processor devices coupled to the master processor device via the SPIs. The master processor device issues commands to the slave processor devices to control operation of the inverter.
