Power generating system with flux regulated generator

A method for generating and regulating direct current (DC) power by means of a single-phase permanent magnet machine (PMM) with a permanent magnet (PM) rotor and a stator with a magnetic circuit that diverts flux within the stator for controlling the output of the PMM, comprising the steps of:

• rotating the PM rotor of the PMM at a velocity sufficient to develop an alternating current (AC) power output from the stator of each PMM;
• transforming the AC output from the stator of each PMM to produce a desired DC power output;
• sensing desired power output parameters of the desired power output;
• generating a control signal for the PMM responsive to the sensed parameters for the desired DC power output;
• and
• applying the control signal to the magnetic circuit that diverts flux within the stator to control the desired DC power output.

A method for generating and regulating alternating current (AC) power with N phases by means of N controlled single-phase permanent magnet machines (PMMs), each with a permanent magnet (PM) rotor and a stator with a magnetic circuit that diverts flux within the stator for controlling the output of the PMM, comprising the steps of:

• rotating the PM rotor of each PMM at a velocity sufficient to develop an alternating current (AC) power output from the stator of each PMM;
• transforming the AC output from the stator of each PMM to produce a desired AC power output with N phases that has a frequency less than the AC power output from the stator of each PMM;
• sensing desired power output parameters for each respective phase of the desired power output;
• generating a respective AC control signal that is lower in frequency than the AC power output from the stator for each PMM responsive to the sensed parameters for a respective phase of the desired AC power output;
• and
• applying each control signal to the magnetic circuit that diverts flux within the stator for each respective PMM to control the desired power output.
