基于四自由度调制的双有源桥电流峰峰值优化
Optimization Analysis of Peak-to-peak Current in Dual Active Bridge Based on Four-degree-of-dreedom Modulation
摘要
Abstract
In order to solve the problem of large peak-to-peak inductor currents in dual active bridge converters with mismatched input and output voltages,a four-degree-of-freedom modulation(FDFM)strategy was proposed by combining symmetric duty cycle modulation and asymmetric duty cycle modulation.By analyzing the operating modes of the four-degree-of-freedom modulation strategy,the peak-to-peak inductor current and transmission power models were established,and the optimal solution with different transmission powers was solved by using the Karush-Kuhn-Tucker(KKT)condition with the peak-to-peak inductor current as the optimization objective.And the experimental prototype was built to verify the effectiveness of the proposed strategy.The experimental results show that the proposed modulation strategy can effectively reduce the peak-to-peak inductor current of the converter and improve the efficiency of the dual active bridge converter.关键词
