摘要
Abstract
Compared with capacitive energy storage circuits,inductive energy storage circuits exhibit significant ad-vantages in pulse parameter(high voltage,short front time,short pulse width,high repetition frequency)and pulse device design(miniaturization,compactness),thus the adoption of inductive energy storage circuits is a competitive low-temperature plasma drive solution.However,the reports of inductive energy storage pulse generators in plasma ap-plications are still limited due to the difficulty in developing high-frequency,high-power opening switches and designing pumping circuits.In this paper,a high-voltage nanosecond pulse generator is developed,which has an output voltage am-plitude of 36 kV,a front time of 6 ns,a pulse width of 8.2 ns,and a repetition frequency of 3 kHz(75 Ω load).It employs a diode opening switch developed by our team and a DOS pumping circuit based on IGBT soft switching technology and cascaded pulse transformers.A plate-plate electrode plasma discharge is successfully driven in the atmosphere using the prototype.The topology proposed in this paper is meaningful for the design of inductive energy storage circuits and low-temperature plasma drive generators.关键词
