摘要： A method for generating and controlling power by means of at least one controlled permanent magnet machine (PMM) with a permanent magnet (PM) rotor and a stator with a magnetic flux diverter circuit for controlling the output of the PMM, comprises the steps of: rotating the PM rotor at a velocity sufficient to develop a high frequency alternating current (HFAC) power output from the stator; transforming the HFAC output to produce a desired non-HFAC power output; sensing desired power output parameters; generating a control signal responsive to the sensed parameters; and applying the control signal to the magnetic flux diverter circuit to control the desired power output.

摘要： A power-conversion control system includes an inverter, a cycloconverter, and a sliding mode controller. The inverter is operable to receive a DC voltage input and produce a first AC voltage output having a first frequency. The cycloconverter has a plurality of bidirectional switches, and is operable to receive the first AC voltage and to synthesize a second AC voltage having a second frequency that is lower than the first frequency. The sliding mode controller is operable to provide a control signal to command the plurality of bidirectional switches to turn OFF and ON when the first AC voltage is at a zero crossing condition. The sliding mode controller is also operable to selectively adjust the frequency and amplitude of the second AC voltage.
