Abstract: An electric motor drive controller for an electric vehicle driven by a motor with permanent excitation and powered by an energy source comprises: a power control stage coupleable to the motor for generating a drive signal at a voltage to control the motor at a desired speed; a voltage control circuit connectable between the energy source and the power control stage for controlling the voltage of the drive signal at a first voltage potential in one operating mode and at a voltage potential greater than the first voltage potential in another operating mode; and a mode controller for controlling the operating modes of the voltage control circuit based on properties of the drive signal.

Abstract: A system and method for driving an electric vehicle is provided. The system has, for example, a power source generating a voltage, a voltage converter, a control system, and one or more motors for driving or propelling the vehicle. The voltage converter is configured to accept an input voltage and generate an output voltage, which is different from the input voltage. The power source provides the input voltage to the voltage converter. A switch is further provided to switch the delivery of power to the control system between a power source voltage and an increased voltage derived from the voltage converter.
