摘要: 提出了一种改进的基于物理-端行为特性的超级电容建模方法,模型包含3部分分支电路,在即时分支电路里,采用了一个电压受即时电路端电压控制的电压源和一时间常数恒定的电容串联来模拟超级电容器的即时特性,同时给出了等效电路的参数确定方法.仿真结果表明,该模型可以精确描述超级电容充放电过程的非线性及充放电之后的电压自恢复特性,具有很好的静态特性和动态特性.该模型简单实用,已成功应用于均衡电路参数优化设计中,并在其它采用超级电容作为能量源的电力电子装置中有很好的应用前景.

Abstract: An ultra capacitor(UC) modeling method based advanced physical terminal behavior was proposed. This model with perfect stable and dynamic characteristics according to the actual physical properties was consisted with three parts of the branch circuits, a voltage controlled voltage source serried by a constant capacitance was used in real-time branch circuit to simulate real-time characteristics of super-capacitors. The method to determine model parameters was also proposed. Simulations results show that this model can well reflect the nonlinear charge and discharge behavior and demonstrate self voltage recovery behavior after charge and discharge. This model has been successfully applied to the optimum design of equalization circuit and it is simple enough to be easily applied for simulation of power electronics applications involving UC practically.
