本文介绍了一种新的对称双电感混合（SDIH）Dickson DC-DC转换器拓扑结构，该拓扑结构适用于需要调节的大转换比，例如直接48 V至负载点（PoL）应用。一个迪克森型开关电容网络被用来有效地产生两个交错的PWM驱动器，大大降低了相对于输入线电压的电压幅度，从而允许减少磁量，同时保持适度的开关频率。偶数阶和奇数阶开关电容网络都可以与直接分相开关一起使用，允许任何一种网络类型实现所有飞电容器的完全软充电。此外，电荷流在所有元件中得到很好的平衡，优选具有相等的电容器和电感器值。随后，这种拓扑结构有望简化元件选择，提高电气和热性能，并降低成本。一个测量为0.176 inch 3的分立式原型显示出非常高的测量功率密度，分别为768 W/in 3、751 W/in 3和598 W/in 3，用于3V、2 V和1V的调节输出电压，同时以750 kHz的频率进行开关。
This work introduces a new Symmetric Dual-Inductor Hybrid (SDIH) Dickson DC-DC converter topology that is suitable for large conversion ratios where regulation is required, such as direct 48V to Point-of-Load (PoL) applications. A Dickson-type switched-capacitor network is used to effectively produce two interleaved PWM drives with a greatly reduced voltage amplitude relative to the input line voltage, in turn allowing magnetic volume to be reduced while retaining modest switching frequencies. Both even and odd order switched-capacitor networks can be used with straight-forward split-phase switching allowing either network type to achieve complete soft-charging of all fly capacitors. Additionally, charge flow is well balanced through all elements, with equal capacitor and inductor values being preferred. Subsequently this topology is expected to simplify component selection, improve electrical and thermal performance, and reduce cost. A discrete prototype measuring 0.176 inch3 demonstrates very high measured power densities of 768 W/in3, 751 W/in3, and 598 W/in3 for regulated output voltages of 3V, 2V, and 1V respectively while switching at a frequency of 750kHz.
