Abstract
An apparatus for controlling the output and torque of a synchronous alternator has a controlled bridge rectifier operable off synchronous for rectifying the alternating output and establishing a desired phase relationship between the alternating voltage and alternating current of the output winding. Phase locked loop control may be employed for establishing and maintaining a desired phase relationship to control the output and torque.
