Abstract
An electrical power system includes a switched reluctance machine/inverter adapted for providing DC power to a load; a voltage controller, which provides a control angle &thgr; to the switched reluctance machine/inverter; an extraction module having an interface to the DC power and providing a resonant frequency content in Park vector format of a resonant frequency content at the interface; a phase locked loop, which provides a transformation angle &thgr; from the resonant frequency content in Park vector format; a resonant frequency voltage controller, which uses the resonant frequency content in Park vector format and the transformation angle &thgr; to provide a control angle &Dgr;&thgr; to the switched reluctance machine/inverter so that the control angle &thgr; and the control angle &Dgr;&thgr; can be used to regulate the DC power and the resonant frequency content is attenuated in regulating the DC power.
