Abstract: An electrical controller for electric rotating machines is provided. A control system for electric rotating machines transmits a controlled quantity of current to or from different windings of the electric rotating machine at any given time. Furthermore, the amplitude of the current is independently variable of the timing and duration of the transmission of the current to or from the windings. This allows increased control of the electric rotating machine and facilitates the operation of the electric motor at high mechanical and/or electrical speeds.

Abstract: A voltage regulation system maintains the output voltage of a permanent magnet generator at an essentially constant level. The stator coils located within the permanent magnet generator are divided into a number of sub-coils. A buck/boost voltage can be applied to selected sub-coils such that the output voltage generated by the permanent magnet generator is increased or decreased. A number of switches are connected to the sub-coils to allow the sub-coils to be connected in a number of different configurations. Connecting the sub-coils in a particular configuration and applying a buck/boost voltage to selected sub-coils based on the monitored output voltage allows the voltage regulation system to maintain an essentially constant output voltage.

Abstract: A vehicle includes an inverter, a pump, a buck converter, and a controller. The inverter has an input connected to a battery and an output connected to an electric machine. The inverter is configured to convert power between DC electrical power at the input and AC electrical power at the output. The pump is configured to circulate lubricating fluid within a transmission. The buck converter is configured to deliver DC electrical power from the inverter to the pump. The controller is programmed to, in response to the electric machine delivering AC electrical power to the inverter during a towing condition of the vehicle while the vehicle is shutdown, operate the buck converter to power the pump.
