Title:
CONTROLLER FOR PERMANENT MAGNET ALTERNATOR
Document Type and Number:
WIPO Patent Application WO2004109892
Kind Code:
A3
Abstract:
The invention is a control system that, among other things, controls a permanent magnet alternator and provides relatively accurate voltage regulation. The control system may include one or more of the following: (1) a rectification system to rectify and regulate the output voltage of an alternator, (2) a rectifier/limiter used as an electrical power source to a boost type regulator, (3) a multimode rectifier/limiter, (4) a DC to AC inverter bridge, and (5) power switches employed in the system to minimize the switching energy that would otherwise be dissipated in the power switches as heat.
