本文提出了一种90.6%的48 V-1 V/150 A的两级混合开关电容负载点(PoL)转换器与24 V的中间总线。转换器的第一级是2:1谐振电荷泵,将48 V输入电压转换为24 V。转换器的第二级是24:1四相串联电容降压转换器,能够通过两个定制的四相耦合电感提供150 A垂直功率传输。两级架构结合了谐振开关电容结构和串联电容降压配置,以实现高效率,高功率密度和电压调节。通过一台48 V-1V/150 A的样机验证了该拓扑的有效性,在60 A时的峰值效率为90.6%,在150 A时的满载效率为86.2%。样机的功率密度为283 W/in 3。
This paper presents a 90.6% 48 V-1 V/150 A two-stage hybrid switched-capacitor point-of-load (PoL) converter with a 24 V intermediate bus. The first stage of the converter is a 2:1 resonant charge pump which converts the 48 V input voltage to 24 V. The second stage of the converter is a 24:1 four-phase series capacitor buck converter which is capable of delivering 150 A with two customized four-phase coupled inductor for vertical power delivery. The two-stage architecture combines the resonant switched-capacitor structure and the series capacitor buck configuration to achieve high efficiency, high power density, and voltage regulation. The effectiveness of the topology is verified by a 48 V-1 V/150 A prototype with a peak efficiency of 90.6% at 60 A and a full load efficiency of 86.2% at 150 A. The power density of the prototype is 283 W/in3.
