Abstract:
A solid-state high voltage regulator circuit for supplying a regulated voltage to a load, the solid-state high voltage regulator circuit comprising:(a) an output terminal coupled to the load;(b) an impedance having a first lead coupled to the output terminal;(c) a high voltage generator coupled to a second lead of the impedance;(d) a voltage divider coupled to the output terminal, wherein the voltage divider is configured to provide a stepped-down voltage indicative of a voltage at the output terminal;(e) an error amplifier coupled to receive the stepped-down voltage and a reference voltage, wherein the error amplifier is configured to generate a control signal indicative of a difference in level between the stepped-down voltage and the reference voltage; and(f) a regulator stage coupled to the error amplifier and the output terminal, wherein, in response to the control signal, the regulator stage is configured to adjust a regulator current flowing from the output terminal through the regulator stage causing a voltage across the impedance to be correspondingly adjusted so that the voltage at the output terminal is maintained at a desired preselected level.
