Abstract
An apparatus and process are provided for regulating the voltage across a resistive or inductive load by phase angle control of the applied load voltage. Instantaneous load voltage is compared with a preset reference value to control the phase angle of the applied load voltage by means of rms voltage approximation feedback control. A visual display can be provided to assist the user in establishing the preset reference value.
