Abstract
PURPOSE:To execute stable control by monitoring an emergizing angle and controlling an ignition angle in case of controlling the AC phase of a load whose power-factor is changed. CONSTITUTION:When disturbance is applied to a load 2 in a voltage controlling circuit 4 and a control variable is changed, a deviation between the output of a control variable detecting circuit 3 and an objective value is generated, and an emergizing angle controlling circuit 7 applies a current supply angle command corresponding to the deviation to an ignition angle controlling circuit 5. The circuit 5 applies an ignition angle corresponding to a deviation between a real emergizing angle detected by an output voltage waveform after the generation of a change in a power factor and an output voltage waveform obtained before the generation of the changed in the power factor to a voltage controlling circuit 4. The circuit 4 starts current supply by an angle based upon an ignition angle command. Consequently, the output voltage can be set up to an objective value and the control variable can be stably controlled.
