摘要

本文分析了作为混合能源电源组成部分的超级电容器尺寸的具体确定方法。定义电源负载的功率随时间的要求，并使用一些近似(线性和常数段的组合，仅用于负载的功率剖面)允许电路解析求解，并找到电容的电压和电流随时间的表达式。这些分析结果可以用来选择超级电容器的尺寸，只假设其初始和最终电压取决于段。所使用的方法允许通过只需要已知负载的功率需求来确定各种应用的超级电容器的尺寸。仿真和实验结果验证了该模型的正确性。

Analytical Model for Supercapacitor Sizing as Part of a Hybrid Power Supply

The paper analyzes the a specific way to size a supercapacitor as a part of a hybrid energy power supply. Defining the load of the power supply by its power over time requirements and using some approximations (combination of linear and constant segments only for the power profile of the load) allows the circuit to be analytically solved and expressions found for the capacitor′s voltage and current over time. These analytical results can be used to choose the supercapacitor size by postulating only its initial and final voltage depending on the segment. The approach used allows for sizing the supercapacitor for wide variety of applications by only requiring the power demand of the load to be known. The model is verified by means of simulation and experimental results.
