Dissertation
High Frequency, High Power Density Integrated Point of Load and Bus Converters
TL;DR: In this paper, the authors explore and propose methods to improve the power de-noise and performance of point of load modules ranging from 10 to 600W by using a three level converter, which can reduce the voltage stress across the devices by a factor of two compared to the traditional buck.
