摘要
针对传统AC-DC-AC在CPT系统(感应电能传输)应用中存在的缺陷,采用双向开关高频直接AC/AC变换技术,提高变换器的变换效率和鲁棒性.对该变换器的工作原理和控制模式进行详细分析,针对变换器电流峰值反馈控制存在的滞后问题,提出变换器的预测控制算法,并结合理论仿真分析,验证该AC/AC变换器控制策略的可行性.
According to the defects of traditional AC-DC-AC in the CPT system （induction power transmis- sion）, a Bidirectional Switch High-frequency AC/AC Direct Converter technology, which uses less power devices to achieve the high-frequency energy conversion, helps improve converter transforming efficiency and robustness. In this paper, analysis on the working principle and control modal of the converter is done. Aiming at the delay problem of the converter of peak current, this paper puts forward the predictive control strategy for the converter, and combining theoretical simulation analysis, it validates the feasibility of the AC/AC Converter.
