摘要

四开关Buck-Boost转换器(FSBB)是一种广泛应用于不需要隔离的DC-DC应用的拓扑结构。这主要是由于它的双向性，以及在宽范围的输入和输出电压下工作的能力。该转换器有几种调制策略，每种策略都有其优点和缺点。本文对几种调制器进行了比较，并计算了晶体管和电感的损耗。有了这些信息，就可以根据设计的FSBB的输入和输出电压、输出功率和硬件限制来选择最佳调制器。

Comparison of several modulation strategies for the Four Switch Buck-Boost converter

The Four Switch Buck-Boost converter (FSBB) is a widely used topology for DC-DC applications in which isolation is not required. This is mainly due to its bidirectionality, and the ability to operate under a wide range of input and output voltages. There are several modulation strategies for this converter, each one with its strengths and weaknesses.In this paper, several modulators from state of the art are compared, and the losses of the transistors and the inductor are computed. With this information, it is intended to select the best modulator depending on the input and output voltages, output power, and hardware limitations of the designed FSBB.
