Abstract

Separate three-phase windings are connected to individual rectifiers arranged for series-parallel switching to improve the current-voltage output characteristic. The common exciter winding is fed through a voltage regulator. The switching of the rectifiers is controllable in response to alternator frequency, output current, temperature or efficiency and may be provided with a manual override switch.
