ABSTRACT:
A power supply having a dual-polarity, automatically switchable high voltage output. The power supply includes apparatus for regulating low voltage including a comparator having a programming voltage input and a feedback voltage input. The low voltage is converted by low voltage dc conversion apparatus to both negative and positive polarity high voltage dc signals proportional to the electronic signal applied to the programming input. Apparatus for switching the high voltage output by remote control is provided such that in a first switching mode the high voltage output is derived from the output of the positive polarity conversion apparatus, and in a second switching mode the high voltage output is derived from the output of the negative polarity conversion apparatus. Finally, apparatus for providing the absolute value of the high voltage output is included and provides a scaled down absolute value of the signal present at the high voltage output which is fed into the feedback voltage input of the low voltage regulator apparatus.
