Abstract

See full text

A system for controlling a high-voltage supply which is inhibited for a time after energization to prevent spurious deenergization. The high-voltage supply includes a source for generating a signal representative of the desired output high voltage. A feedback voltage control responds to this signal and controls the high-voltage supply. The system includes a source for developing a linear ramp signal which varies from an initial value at which the output of the high-voltage generator is under the control of the ramp signal source to a value at which the output of the high-voltage generator is under the control of the signal representative of the desired output high voltage.
