摘要
以DC-DCBuck-Boost开关变换器在变速恒频风力发电中的实际应用为研究背景,给出了对Buck-Boost变换器进行动力学建模与应用经典电路分析相结合的变换器母线电容参数设计方法。首先基于Buck-Boost变换器拓扑结构建立精确的数学模型,再根据此模型参数摄动的动力学仿真来判断应用经典电路分析法所获得的变换器参数的可行性,进而给出合理的参数取值。仿真与实验结果验证了所提出的Buck-Boost变换器参数设计方法的正确性。
Considering the engineering application of DC DC BuckBoost switching converter in variable speed constant- frequency wind power generating, a method to combing the dynamic modeling and the classical circuit analysis modeling to design the parameter of the bus capacitor in DC-DC Buck-Boost converter is proposed. Based on the topological structure analysis of the Buck Boost switching converter, its mathematical model is derived firstly. Then the feasibility of the converter parameter obtained by classical circuit analysis method is checked according to the dynamic simulation results of parameter perturbation. Finally the reasonable parameter is obtained. The proposed method is validated by simulation and experiment results.
