CONTROL SYSTEM FOR PHASE DISPLACEMENT REGULATOR CIRCUITS ABSTRACT OF THE DISCLOSURE A control circuit for a regulator circuit of the type in which the regulator output voltage and current are dependent upon the phase angle between an unregulated a-c input voltage wave and a regulating or control voltage wave. The control circuit generates a reference signal that is locked in phase with the a-c input voltage wave and a control signal that is locked in phase with the control voltage wave. Output voltage sensing circuitry is arranged to increase or decrease the phase angle between the control signal and the reference signal, as required, to maintain the output voltage of the regulator at the desired, regulated value. A phase difference limiting network allows the control signal to vary freely in phase with respect to the reference signal so long as the control signal remains within an angular window of from 0° to 60° of lag behind the reference signal and assures that limits of this angular window cannot be exceeded. A damping signal is utilized to assure that the rate of change of the phase angle between the control and reference signal is limited in a manner which affords both high control system stability and rapid dynamic response to changes in input voltage and output current. OR-ing circuitry is also provided to allow the output current to reduce the regulator output voltage and thereby limit the regulator output current to a safe value when the output current attempts to rise beyond its highest rated value.
