摘要： 目的：介质阻挡放电（DBD）电源已在化工、生物、医疗等诸多领域得到研究与应用。在小功率DBD电源中，变压器寄生电容相对负载等效电容来说不可忽略。因此需要研究寄生电容对放电特性的影响，从而针对给定的放电参数和负载给出一个简单准确的电源设计过程。
创新点：利用整流补偿基波近似法（rectifier-compensated first harmonic approximation, RCFHA）将DBD等效负载电路线性化，从而得到新的线性等效电路。基于此线性等效电路，分析变压器寄生电容对电路的影响并总结电源设计过程。
方法：提出一种新的DBD负载线性等效电路；分析变压器寄生电容对放电特性的影响；给出电源参数设计方法。
结论：仿真和实验结果证明分析和设计过程的准确性（图10-12）。利用所提设计方法，可以对小功率DBD电源进行准确的参数计算。

Abstract: For low power dielectric barrier discharge (DBD) used in small-size material treatment or portable devices, high-step transformer parasitic capacitance greatly influences the performance of the resonant converter as it is of the same order of magnitude as the equivalent capacitance of DBD load. In this paper, steady-state analysis of the low power DBD is presented, considering the inevitable parasitic capacitance of the high-step transformer. The rectifier-compensated first harmonic approximation (RCFHA) is applied to linearize the equivalent load circuit of DBD at low frequency and the derived expressions are accurate and convenient for the analysis and design of the power supply. Based on the proposed linear equivalent load circuit, the influence of transformer parasitic capacitance on the key parameters, including the frequency range and the applied electrode voltage, is discussed when the power is regulated with pulse frequency modulation (PFM). Also, a design procedure is presented based on the derived expressions. A prototype is constructed according to the design results and the accuracy of the design is verified by experimental results.
Key words: Dielectric barrier discharge    Rectifier-compensated first harmonic approximation    Parasitic capacitance    Power converter design
