Rapid Automated Point-of-Care System (RapiDx)
Miniature High-Voltage Power Supply and Miniature High-Voltage Controller
Microfluidic Devices
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.
