Power Supply Regulation by Microprocessor

By: Langenbach, H.; Sheehan, J.;

1983 / IEEE


This item was taken from the IEEE Periodical ' Power Supply Regulation by Microprocessor ' Many small magnet power supplies are regulated by using a microprocessor system to generate control voltages to continuously servoregulate each power supply. The power supplies are of very simple design since all regulation and feedback hardware are parts of the microprocessor system. Most of the supplies are bipolar transistor followers, powered by a common unregulated D. C. power supply and are used to power trim steering magnets on the three NSLS synchrotron rings. Twelve bit accuracy is obtained using commercially available microprocessor P.C. cards.
