ABSTRACT:
A voltage regulator and flicker compensator is taught which utilizes a simulated light bulb in the feedback control. The simulated light bulb utilizes an analog voltage squaring module the output of which is filtered to reduce the second harmonic of the input signal. An error generator is provided as part of the control loop. The error generator utilizes an adaptive voltage reference which tends to conserve VAR generator capacity. A voltage preconditioner is also utilized which reduces spurious non-flicker transients and the like in the feedback signal.
