Abstract
A circuit for controlling the application of power from a source thereof to a load. In this controlling circuit, a phase control circuit is provided for supplying current from the source to the load for varying voltage applied to the control node to maintain the effective voltage near a preferred value despite variations in the voltage of the source. An initializing circuit is also provided for preventing the application of excessive voltage to the load upon the initial energization of the controlling circuit.
