Abstract

See full text

A high-voltage power supply system for a mass spectrometer comprises a ground-referenced power supply with a first transformer having a primary winding and a secondary winding, the primary winding is electrically coupled to a first source of AC power, and a floated bias voltage power supply with a second transformer having a primary winding and a secondary winding, the primary winding of the second transformer is electrically coupled to a second source of AC power. A return electrical path of the floated bias voltage power supply is electrically coupled to the ground-referenced power supply to bias an output voltage of the ground-referenced power supply. A floating shield is around the floating bias voltage power supply, and at least one resistive element is in the return electrical path of the floated bias voltage power supply to reduce noise coupled from the floated bias voltage power supply to the ground-referenced power supply.
