摘要
基于电路的输出效果,采用电荷转移原理阐述平衡式Cockcroft-Walton(C-W)倍压电路较为复杂的物理过程,将电路中二极管的非线性导通特性等效为周期性线性导通的数学解析模型,推导了表征其输出特性的纹波电压和带载输出电压的理论输出表达式。采用仿真软件对比了基本式和平衡式C-W电路的输出特性曲线,结果表明平衡式拓扑结构的纹波大小约为基本式拓扑结构的8%。同时建立的多阶平衡式C-W电路纹波电压理论模型计算值略低于电路软件仿真值,带载输出电压的理论模型计算值与仿真值的相对误差低于10%。
Based on the output effect of the circuit,the study used the charge transfer principle to describe the relative complex physical processes of balanced Cockcroft-Walton（C-W）circuit.Given the periodically turning model to mathematical analysis is equivalent to nonlinear conduction properties of the diode,theoretical model output formulas of ripple voltage and load-dropping output voltage that describe the output characteristics of C-W circuit are derivated.With circuit simulation software,the ripple voltage and the output voltage waveforms of the basic and balanced C-W circuit are simulated,and it illustrates that the ripple voltage of the balanced topology is far less than the basic,approximately the value percentage of 8%.The outputs of the theoretical model established in this paper are verified,and the results show that the calculated ripple voltage from the theoretical model is slightly lower than the simulation values,and the relative error between the calculated output voltage and simulation values is less than 10%.
