    摘要： Systems and methods are disclosed for a DC boost converter. The systems and methods combine operation of an inductor with the input capacitor of a DC/AC inverter via a switch configuration to power the DC/AC inverter. The switch configuration is controlled by a plurality of control signals generated by a controller based on a variety of control modes, and feedback signals.

    摘要： Methods and apparatus are provided for rotor and stator temperature compensation for field weakening current. The method comprises generating a phase voltage feed back signal Vph based in part on pre-defined optimal current commands (ID* and IQ*) received by the IPM, generating a phase voltage command (Vphcmd) based in part on a temperature of a magnetic rotor and stator of the IPM, and generating a phase voltage error (Verror) by subtracting the phase voltage feed back signal (Vph) from the phase voltage command (Vphcmd). The method further comprises generating a d-axis command current correction value (ΔId) and a q-axis command current correction value (ΔIq) from the phase voltage error (Verror); and adjusting the pre-defined optimal current commands (ID* and IQ*) by the d-axis and the q-axis command current correction values (ΔId and ΔIq).

    摘要： 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.
