汽车48V串联电容降压变换器中LC相间动力学的主动阻尼

This article presents a 4:1 series-capacitor buck (SCB) converter designed for automotive 48$ \,\mathrm{V}$-to-0.8$ \,\mathrm{V}$ applications, targeting improved transient response under rapid input voltage variations. The proposed design addresses the inherent interphase $LC$ oscillations in hybrid dc–dc converters through a novel dynamic flying-capacitor voltage tracking technique. Unlike conve...
