High conversion ratio (HCR) step down DC-DC converters are gaining growing attention for usage in these high tech emerging applications. The main design challenge of these converters is maximizing conversion ratio, efficiency, and power density simultaneously. In this paper, we have advanced and expanded design procedure for Quasi Square Wave (QSW) buck converter, which is promising candidate to overcome aforementioned challenges. The procedure is essential for precise calculation of design parameters and components selection to avoid iterations after implementation. We also introduce development of an optimization approach based on detailed power loss analysis. We utilized this approach here to design optimum LS and HS FETs; and obtain power loss break down. The 1 MHz designed buck converter steps down voltage from 48 V to 1.8 V at 30 A of output current.}, booktitle={2017 IEEE 5th Workshop on Wide Bandgap Power Devices and Applications (WIPDA)}, author={Naeimi, Y. and Huang, A.}, year={2017}, pages={148–152} }
