ABSTRACT:
A control system for power delivered to an inductive load includes automatic control with a manual override for emergency situations. The system monitors the power delivered to the load and varies the power delivered to the inductive load by controlling the phase difference between the voltage and current delivered to the load. Feedback to the control system automatically controls the phase difference between voltage and current in response to the measured power delivered to the load. Provision is made for introducing an external signal into the feedback circuit, whereby the external signal supersedes the automatic control of the power delivered to the load.
