摘要
针对等离子体及其应用对于高可靠性、小型化高压重频脉冲电源的需求,研制了一种基于感应叠加原理的模块化脉冲电源。该脉冲电源采用绝缘栅门极晶体管(insulated gate bipolar translator,IGBT)作为主开关,基于脉冲变压器升压和感应叠加原理实现多个单元模块的脉冲电压叠加,从而获得高压短脉冲。首先基于PSpice软件验证该拓扑结构的可行性并为元件选型提供理论指导,最终研制出基于感应叠加原理的脉冲电源的样机,其输出脉冲参数为:幅值为0~15 kV可调,重复频率为1~10 kHz可调,脉宽为5~7μs。脉冲电源采用模块化设计,在保证各模块之间绝缘的前提下,可以通过增加模块数量方便地提高最大输出电压。依托该脉冲电源开展介质阻挡放电(dielectric barrier discharge,DBD)等离子体试验,验证了该脉冲电源产生等离子体的可靠性。
To meet the demands of plasma and its application for high-reliability and miniaturized high-voltage repetitive frequency pulse power supply, a modular pulse power supply based on the principle of inductive adder is developed. In the pulse supply, an insulated gate bipolar translator(IGBT) is used as the main switch, and the pulse voltage overlay of multiple units is realized based on the principle of pulse transformer boost and inductive adder so as to obtain high-voltage short pulses. The feasibility of the topology structure is verified firstly based on the PSpice software so as to provide theoretical guidance for component selection.Finally, a prototype of pulse power supply based on principle of inductive-adder is developed, whose output pulse parameters are as follows: the amplitude is 0 to 15 kV adjustable, the repetition frequency is 1 to 10 kHz adjustable, and the pulse width is 5 to 7 μs. The pulse power supply is designed in modular, and the maximum output voltage can be easily increased by adding the number of modules on the premise of ensuring insulation between modules. Moreover, the dielectric barrier discharge(DBD) plasma experiment is carried out by using the pulse power supply. The reliability of plasma generated by the pulse power supply is verified.
