一种用于电池充电器应用的开关电感混合降压DC-DC转换器

This letter presents a switching-inductor hybrid dc-dc converter designed for battery charger applications, operating with a 5 V input and an output range of one-cell battery (3–4.3 V). The hybrid converter effectively reduces the rms inductor current compared to conventional buck and three-level buck converters, enabling the use of a compact inductor while maintaining high efficiency. The design ...
