Abstract
An AC line voltage regulator having a voltage sensing circuit for sensing and producing signals representative of the difference between a predetermined voltage level and the line voltage level and a load current sensing circuit for sensing and producing a signal representative of the magnitude of a load current drawn from the regulator. An actuation circuit combines the signals produced by the voltage and current sensing circuits to control the timing of a selectively switchable dispensing circuit which dispenses energy into an oscillatory circuit oscillating at the line voltage frequency and connected between input and output ports of the regulator. The dispensing circuit permits a selectable amount of energy to be dispensed in the oscillatory tank to adjust the line voltage level by adding the energy to either buck or boost the line voltage as determined by the difference signal. The magnitude of the dispensed energy is determined by combining the line voltage and load current signals to produce an activating signal, which permits the dispensing circuit to add energy at a predetermined rate for a period of time determined by the activation signal.
