Abstract

See full text

An AC power supply drives and controls an array of non-thermal plasma emitters at desired frequencies at a controlled power level. The power supply comprises a step-up transformer, a balanced driver, and a controller. The transformer operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The balanced driver may be driven directly by the controller. The controller monitors the phase relationship between the transformer primary winding voltage and the gate drive voltage, and adjusts the drive frequency to resonance. Alternatively the balanced driver is configured as an oscillator which drives the transformer at resonance by default. A signal from the transformer driver generates an interrupt to the controller for synchronizing current and voltage measurements for power control.
