    Abstract: A surface-mounted permanent magnet synchronous machine drive and a method of controlling the machine drive. Flux weakening and current regulating loops cooperate to provide automatic transition to the flux weakening mode (operation above base speed), regardless of DC bus voltage, load or other operating conditions. The modulation index (d) is used as a condition for automatic start of flux weakening operation is very useful because this point can be easily changed by software when necessary, regardless of the value of DC bus voltage. This feature provides significant performance improvement. No look-up tables are used in the flux weakening loop. The on-set point for flux weakening is automatically adjusted, and may be changed through software. An appropriate d-axis current component is injected over the entire speed range, providing the maximum available torque (which corresponds to the q-axis current component).

    Abstract: Methods and apparatus are provided for improved discharge of a DC bus which provides power to an inverter. An electric motor system provided with the improved discharge method for discharge of the DC bus includes an electric motor, the inverter which provides electric control for the permanent magnet electric motor, the direct current (DC) bus which provides power to the inverter, and a processor. The processor generates operational control signals and provides such operational control signals to the inverter. In response to detecting a predetermined discharge signal, the processor generates operational control signals for generating a ripple current in motor windings of the electric motor to dissipate energy from the DC bus through a passive load, the passive load including the motor windings of the electric motor.

    Abstract: Methods and systems are provided for modeling temperature characteristics of components in a system such as a power module for a hybrid or electric vehicle. A power dissipation value is calculated for each of the components in the system. A first filter is applied to the power dissipation value associated with a selected component to determine its estimated temperature. For each of the neighboring components located adjacent to the selected component, a cross-coupling temperature is estimated by applying other filters to each of the power dissipation values for the neighboring components. The estimated temperature of the selected component and the estimated cross-coupling temperatures for each of the neighboring components can then be added to thereby estimate the operating temperature for the selected component. Further, the operation of the system may be adjusted if the operating temperature determined for the selected component exceeds a threshold value.
