Abstract
The present invention provides shunt voltage regulation by employing a rectifying means to rectify an incoming signal and a current sinking means to divert current from the output of the rectifying means in such a way that the output voltage is maintained at an appropriate level and the modulation level does not rise above the acceptable range. This is accomplished by having two feedback mechanisms for the control of said current sinking means. A first feedback mechanism utilizes a voltage dividing means to generate a control voltage signal that will cause the average output voltage of the rectifying means to be equal to the a reference voltage. A second feedback mechanism utilizes non-linear processing means and capacitors to transmit part of the modulation frequency to the control of the current sinking means, thereby keeping the modulation at the output of the rectifying mean at an appropriate level at all time.
