Abstract
The present invention provides an electro-mechanical energy exchange system with a variable speed synchronous reluctance motor-generator having an all-metal rotor. A bi-directional AC-to-DC electric power converter interconnects the motor-generator with a DC bus. First and second hybrid controllers provide current regulation for the motor-generator and voltage regulation for the DC bus. Use of both feedback and feedforward control elements provides a controller particularly suited for operating high speed devices.
Claims1
An energy conversion system comprising:
- a bi-directional AC-to-DC electric power converter;
- the converter electrically interconnecting and bi-directionally exchanging electric power between a variable speed synchronous reluctance motor-generator and a DC bus;
- the motor-generator bi-directionally exchanging mechanical power with a flywheel;
- the power exchange being controlled by a plurality of current controllers;
- the current controllers operably coupled to the converter;
- the current controllers including a feedforward controller and a feedback controller
