Abstract
A system and method to smoothly limit the top speed of the generator motor at which power is provided. The system according to this invention consists primarily of an engine, which supplies mechanical power to a switched reluctance motor with position sensing capability, which delivers electrical power to an inverter. The inverter contains a digital signal processor (DSP) controller to control the delivery of electrical power to the battery in the generation mode. Signal information regarding motor speed and current is delivered from the switched reluctance motor with position sensing capability to the DSP controller and signal information regarding current and voltage is delivered from the battery to the DSP controller. In the preferred embodiment, the switched reluctance machine will have position sensing capability to monitor the position of the rotor in relation to the stator, and sensors to monitor the phase currents and bus current. A digital signal processor (DSP) will be used in order to meet the precise position-based control requirements. Therefore, since the position and current is monitored and controlled in real-time by the DSP, the power output in the generation mode …
