Abstract
An alternating current power control circuit utilizing progressive variation of magnetic flux in associated magnetic paths. Voltage and current sensors at an output provide feedback signals to permeance control devices to apportion flux between a pair of magnetic paths such that the primary magnetizing current remains essentially unchanged during the control process.
