Abstract
A combined high voltage power supply regulator and modulator which may be used with, for example, voltage tuned microwave devices. The circuit is characterized by a capacitively coupled variable impedance comprising fast acting semiconductor devices which are disposed in the low voltage return leg of the power supply to facilitate biasing. The variable impedance is controlled by a feedback signal to remove unwanted power supply ripple and may also be controlled by a wide variety of modulation signals to produce a modulated voltage for application to the voltage tuned microwave device.
