Claims12
A permanent magnet (PM) generator assembly comprising;
- a PM generator having magnetic flux control windings and a power output;
- a passive rectifier, having a rectifier output, connected to the power output of said PM generator;
- a passive control element electrically connected to the rectifier output of said passive rectifier and said magnetic flux control windings.
A passive permanent magnet (PM) generator control system comprising a passive rectifier connected to a rectifier output bus and a passive control element connecting the rectifier output bus to a control winding within the PM generator.
A method for passively maintaining a permanent magnet (PM) generator output voltage comprising the steps of;
- converting a portion of a PM generator output voltage into a current;
- and
- generating a magnetic flux within said permanent magnet generator based on said current.
