Control System for a Power Supply

FEATURES
Power supplies are used in numerous devices and applications as sources for voltage and/or current. In some devices, such as mass spectrometers, the accuracy of the voltage output of a power supply is a consideration in the overall performance of the device. Voltage drift and noise can adversely affect the accuracy of the voltage output.

The invention is a control system for a power supply that includes a control circuit and a feedback circuit. The feedback circuit is configured to produce a feedback signal indicative of the voltage of the power supply output. The control circuit is configured to control the power supply based on the feedback signal and a predetermined voltage value to maintain the output of the power supply at the predetermined voltage value. In addition, a portion of the feedback circuit may be included in an isolation shield to improve the accuracy of the feedback circuit.

BENEFITS
Output voltage is maintained at the predetermined voltage value.
