摘要
针对现有的介质阻挡放电(dielectric barrier discharge,DBD)负载供电电源难以发挥DBD负载性能这一现状,该文提出一种适用于介质阻挡放电负载的紧凑型脉冲供电电源。这种供电电源通过在现有基于反激电路的供电电源中引入反馈二阶管,可有效避免基于反激电路的供电电源出现的DBD负载电压震荡现象,且能为DBD负载提供高电压上升率的高频高压脉冲激励。此外,由于这种电路衍生于反激供电电源,因而继承了反激供电电源结构紧凑的特点。根据这种供电电源的工作过程,该文进行了详细的模态分析,并得到这种供电电源的特性。为验证理论分析的正确性,以DBD型准分子灯为负载对供电电源性能进行测试,实验结果表明,供电电源不仅可以为DBD负载提供电压平均上升率为4.521×10;V/s的脉冲激励电压,而且具有工作频率高、功率开关器件工作于软开关状态的特性。该紧凑型脉冲供电电源可为传统DBD负载供电电源改造提供一种方案。
The traditional power supply for dielectric barrier discharge(DBD)load is difficult to exploit the DBD load’s performance.In order to address the question,a compact pulse power supply suitable for DBD load was proposed in this paper.The kind of the power supply effectively can avoid the load voltage oscillation in DBD load,and a high-frequency high-voltage pulse excitation with high rise rate for DBD load can be achieved with a feedback diode.In addition,because this circuit is derived from flyback power supply,the characteristic of compact structure,which originates with flyback power supply,was inherited.According to the working process of the power supply,a detailed modal analysis was carried out in the paper,and the characteristics of the power supply was obtained.In order to validate the theoretical analysis,a power supply for DBD type excimer lamp was tested and the experimental results show that a pulse excitation voltage with an average voltage rise rate of 4.521×10;V/s for DBD load can be obtained.Beside these,the power supply has some additional excellent characteristics such as high working frequency and soft switching state of power switch.Therefore,the compact pulse power supply used in this paper can be used for the improvement of traditional power supply for DBD load.
