Abstract:
A power regulator for use with an AC power source comprising:a voltage converter having a first input and a second input, the first input being connected with the AC power source and receiving AC current therefrom and the second input being connected with a controller and receiving a control signal therefrom, the voltage converter generating a substantially sinusoidal regulator output signal, the amplitude of which is responsive to the control signal; and a controller having a first input and a second input, the first input receiving the regulator output signal and the second input receiving a set point signal, the set point signal determining the amplitude of a substantially sinusoidal reference signal, the substantially sinusoidal reference signal being substantially in-phase with the regulator output signal, the controller generating the control signal indicative of the instantaneous difference between the regulator output signal and the amplitude of the substantially sinusoidal reference signal wherein the amplitude of the substantially sinusoidal reference signal is independent of the amplitude of the AC power source and the amplitude of the regulator output signal.
