Abstract

A high voltage power supply for use in a system such as a microfluidics system, uses a DC—DC converter in parallel with a voltage-controlled resistor. A feedback circuit provides a control signal for the DC—DC converter and voltage-controlled resistor so as to regulate the output voltage of the high voltage power supply, as well as, to sink or source current from the high voltage supply.
