A 90.6% Efficient, 0.333 W/mm2 Power Density Direct 48V-to-1V Dual Inductor Hybrid Converter with Delay-line Based V2D Controller

This brief presents a 48V-to-1V 10-level dual inductor hybrid converter (DIHC) containing 11 on-chip switches and an off-chip gallium nitride (GaN) switch. Thanks to the 10-level Dickson switched-capacitor (SC) circuit, most of the voltage stress will be taken over by off-chip capacitors, which reduces the voltage stress of each switch to 4.8...

High efficiency, highly integrated DC-DC converter for 48V data centers with standard CMOS and GaN devices

This thesis presents a 48V-to-1V 10-level dual inductor hybrid converter (DIHC) containing 11 on-chip switches and an off-chip Gallium Nitride (GaN) switch. Thanks to the 10-level Dickson switched-capacitor (SC) circuit, most of the voltage stress will be taken over by off-chip capacitors, which reduces the voltage stress of each switch to 4.8 V...

Isolated DC/DC Converters for DC Distribution Grids in Rural Electrification

Roughly 840 million people, predominately from rural communities in sub-Sahara Africa, still lack access to electricity. The direct current (DC) microgrid is an emerging grid infrastructure that meshes efficiently with DC based technology such as photovoltaics, batteries, consumer electronics, and electric vehicles. This characteristic of DC...
