热声发电系统蓄电池负载的最大功率控制策略
Maximum Power Control Strategy of Thermoacoustic Power Generation System with Battery Load
摘要
Abstract
Thermoacoustic power generation system has the merits of high thermal conversion efficiency, reliable operation and low environmental pollution. However, if the battery is charged by the linear generator in the direct way, the system works only when the output voltage of the generator is higher than the terminal voltage of the battery, and the transfer efficiency is relatively low. Buck-boost converting circuit is used in this paper to transform the output voltage of the linear generator, in order to make the battery get the maximum power, and then to improve the efficiency of the thermoacoustic power generation system. The dynamic equations of the system are analyzed, and then the maximum power control strategy of the battery load is obtained. The simulation results show that with the proposed control strategy, the power received by battery is more than twice of the one with the traditional way.关键词
