High-frequency high-voltage low-temperature plasma generating system

Abstract

The invention relates to a high-frequency high-voltage low-temperature plasma generating system that comprises a control circuit, a zero voltage soft switching driving circuit and a high-frequency resonant step-up circuit, wherein the control circuit is used for transmitting a control signal to the zero voltage soft switching driving circuit; the zero voltage soft switching driving circuit receives the control signal, inverts the control signal into an AC signal, and transmits the first step-up signal to the high-frequency resonant step-up circuit after performing a first step-up process through the zero voltage soft switching driving circuit; and the high-frequency resonant step-up circuit receives the first step-up signal and performs a second step-up process on the first step-up signal.By adding the zero voltage soft switching driving circuit and the high-frequency resonant step-up circuit to the system, the control signal becomes the first step-up signal, and the first step-up signal is boosted by the high-frequency resonant step-up circuit to form a high-voltage electric field. Finally, a low-temperature plasma is stably formed in the high-voltage electric field, thereby achieving an effect of generating plasma at high efficiency, low loss, and low temperature.
