Power control strategies evaluation of a series resonant inverter for atmosphere plasma applications

A prototype of a high-voltage high-frequency power supply for atmosphere plasma applications such as dielectric barrier discharge and corona-discharge is presented. It is consisted of a rectifier accompanied power factor correction function (PFC) and a resonant inverter. Some technologies, including pulse-amplitude modulation (PAM), pulse-width modulation (PWM), pulse-density modulation (PDM) and pulse-frequency modulation (PFM) have been tested to evaluate the power control performances. Experimental results show that the diversity among these methods and a hybrid control is suggested in accordance with these applications.
