Abstract :
In this letter, the properties of three-level dc/dc converters when used as switch-mode power supplies are investigated to see how they compare to those of two-level converters and to see if they can be used to improve light load efficiency. The letter compares the two converters and uses experimental results to make conclusions about light load efficiency.
