20060038539 - Electric machine: A method and an apparatus are described for monitoring a rotating synchronous electric machine (9), which comprises a rotor winding and a stator having a stator winding. The method comprises the steps of determining the stator winding current, determining the stator winding voltage, determining the rotor winding current, and estimating...

20060038541 - Regulator control circuit and method: Switching devices control the rectification and flow of alternating current power from a source such as an alternator to a load such as a battery in response to both the voltage of the battery and a minimum selected time period that is selected to eliminate or reduce an imbalance between...

20060038540 - Systems and method for boosting output of an alternator: Disclosed herein are two techniques, neutral point switching and field voltage boost, that will increase the output of today's 12 volt automotive electrical systems in vehicle idle conditions solely by the addition of circuitry. Neutral point switching enables the flow of a third harmonic current, which does not normally flow...

20060033478 - Fault tolerant architecture for permanent magnet starter generator subsystem: A permanent magnet starter/generator subsystem configured in a fault tolerant architecture is described herein for small engine applications. The system allows for lighter system weight, improved system reliability, higher performance capability and reduced maintenance....

20060028184 - Control system: A control system comprising a control input device having a movable magnet, a pole-piece frame arrangement positioned about the magnet and positioned therein at least two magnetic flux sensors for sensing movement of the magnet in a given direction. The control system further comprises a monitoring arrangement for monitoring the...

20060022647 - Vehicle-mounted electric generator control system which selectively supplies regenerative field current to battery in accordance with currently available generating capacity: A control apparatus for a vehicle electric generator judges the currently available generating capacity of the generator and establishes a regenerative current mode of operation, utilizing an induced current of the field winding, only when the generating capacity is estimated to be below a predetermined level. The control apparatus also...
