| 摘 要： | 寄生参数参与谐振使得谐振型高压直流电源参数设计困难,为了简化设计,详细讨论了考虑寄生参数的谐振型高压直流电源工作特性,提出了直接采用变压器分布电容作为并联谐振电容的设计思路,建立了基于基波分析法的简单实用的R-C等效负载模型.仿真证明了该模型在较大的频率范围内具有很好的精度,在此模型的基础上提出了设计电路谐振参数与工作频率的图表法,根据该方法设计了直接利用寄生参数作为谐振参数的80 kV/80 kW的高压直流电源.实验证明利用该方法能够达到较好的设计效果.

| Abstract: | The design of high-voltage DC power supply is quite difficult because of the influence of distributed capacitance.The working characteristics of resonance-type high-voltage DC power supply are analyzed considering the distributed capacitance and the distributed capacitance of transformer is directly taken as the parallel resonance capacitance in the design.A simple and applicable R-C load model is established and simulation result shows its high precision in wider range of frequency,based on which,a graphic... |
