METHOD AND APPARATUS FOR REGULATING HIGH VOLTAGE

摘要

A method for regulating output of a high voltage generator includes monitoring a voltage output of the generator and comparing it to a voltage setpoint to generate an error signal. A load on the generator is monitored to generate a load signal. The load signal is conducted to a feedforward signal generator. The feedforward signal generator is configured to produce a feedforward signal corresponding to the load and to at least one parameter related to an output impedance of the high voltage generator. The error signal is conducted to a high voltage regulation loop. The control loop output and the feedforward signal generator output are coupled to a driver for the high voltage generator.
