英文摘要：

The paper first analyzes the principle of AC electronic load simulator based on single phase full bridge topology and introduces the one cycle control strategy of the load simulator. It then carriesout the simulation. The performance of one cycle control strategy and PID control strategy is compared from two aspects of load simulation accuracy and dynamic response speed. The one cycle control method of single phase full bridge AC/DC topology can not only improve electronic load simulation accuracy greatly, but also suppress power interference quickly. The results show that the one cycle control strategy of AC load simulators is effective and practical.
