Dynamic performance analysis of 3-level integrated buck converters
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015•ieeexplore.ieee.org
A systematic analysis of 3-level integrated buck converters is conducted in this paper.
Detailed derivations of the working principles, voltage conversion ratio and output voltage
ripple are given. In particular, the system loop gain of 3-level buck converters is analyzed,
which provides guidance on designing fast and robust 3-level converters. The derived loop
gain is verified with time-domain small signal injection analysis. The results show a good
match between analytical and simulation results.
