摘要

这种拓扑结构有可能在输出电压处提供小纹波，对负载变化的快速响应，以及在高负载电流条件下的高效率。利用MATLAB仿真了带降压变换器(BBBC)的升压变换器和带降压变换器(SBBC)的SEPIC变换器。在本研究中，比较了BBB和SBB转换器的性能。输出波形用于纹波因子的计算。与普通升压与降压变换器相比，带有降压变换器的SEPIC的性能明显更好。在降压升压变换器中，波纹大量存在。这种纹波有可能产生谐波，消除这些谐波通常需要使用相当大的电容器或LC滤波器。

Selection of DC-DC Converters for PV-Battery based Hybrid Systems

This topology has the potential to provide a small ripple at the output voltage, quick responses to variations in load, and high efficiencies under conditions of high load current. MATLAB is used to simulate both boost converters with buck boost converters (BBBC) and SEPIC converters with buck boost converters(SBBC). In this study, the performance of BBB converters and SBB converters was compared. The output waveform is used in the calculation of the ripple factors. When compared to normal boost with buck boost converters, the performance of SEPIC with buck boost converters is significantly better. Ripples are present in large amounts in a buck with buck boost converter. This ripple has the potential to generate harmonics, and the elimination of these harmonics typically requires the utilization of a sizable capacitor or an LC filter.
