摘要
Abstract
Aimed at the problems of a traditional dual-active-bridge(DAB)converter such as large switching loss,large circulating current,narrow range of load variation and low operating efficiency,a novel power control method for DAB converter based on variable inductance and phase shift(PS)angle is proposed,in which the variable inductance and PS angle are taken as the main control parameters to improve the operating efficiency of the DAB converter in a wider range of load variations.In addition,the transfer function of the DAB converter is linearized to improve the practicality and convenience of the controller.Because the device saturation is controllable in the proposed method,the core size can be reduced to optimize the converter size.Finally,the effectiveness and superiority of the proposed method were verified by experiments.Results show that under the condition of maximum PS angle,the inductance variation significantly affected the power transmission of the DAB converter,and its overall operating efficiency was about 5%higher than that of the traditional DAB converter under both the light and heavy load conditions.关键词
