摘要 以燃料电池用交错并联型Boost变换器为研究对象,该文提出一种兼顾效率与功率密度的参数综合设计方法。首先对比单支路运行和多支路交错运行的电压及电流纹波,引入纹波抑制比量化交错并联对纹波的影响,从而建立变换器整体纹波要求与支路参数的对应关系,以此为基础进行参数设计。在参数设计过程中,以开关频率fs、电感电流纹波ΔIL以及电感磁心半径r为自变量,进行损耗建模和无源器件体积建模。以变换器损耗小于设定值为约束条件,以无源元件体积和最小为目标,优选最佳参数。在此基础上,进行电容取值和电感设计,进而实现兼顾效率和功率密度的设计目标。最后,通过仿真及搭建40kW实验样机,验证了理论分析的正确性和参数设计方法的可行性。

Abstract:Taking the interleaved boost converter for fuel cell as the research target, a comprehensive parameter design method is proposed considering efficiency and power density. Firstly, the voltage and current ripple are compared in single-branch and multi-branch interleaved operation. Ripple suppression ratio is introduced to quantify the effect of interleaved structure, thereby establishing the relationship between the ripple requirement and parameters of the single branch, and consequently the parameter design is carried out. During the process of comprehensive design, the switching frequency fs, the inductor current ripple ΔIL and the radius of inductor core r are chosen as independent variables to establish the power loss and passive device volume model. Power loss less than the set value is set as the constraint condition, the minimum volume of passive components is the design object, the optimal independent variables are chosen. Then, the optimal value of the capacitor and the design of the inductor are carried out, and the comprehensive design considering efficiency and power density is achieved. Finally, the correctness of theoretical analysis and the feasibility of the parameter design method are verified via the simulation and a 40kW prototype.
