多电平双向BUCK—BOOST直流变换器的研究

本文对多电平双向Buck—Boost直流变换器的特性进行了较为详细的讨论，解决了传统两电平双向变换器的缺点，提高了变换器的动态响应，起到了优化整个系统的动态特性的作用。

This paper proposes a Multilevel Buck-Boost DC-DC converter. The main circuit topology of the Buck-Boost DC-DC TL converter is analyzed in details. The operation principle is discussed.and the characteristics of the converter are derived to solve the traditional two-level bi-directional converter disadvantage. The dynamic response of the converter is improved and the dynamic role properties of the whole system has been Optimized.
