Single-phase, two-phase and three-level buck converters were evaluated over a wide range of outputs using analytical models and measurements. The converters\' performance is evaluated at all operating points using statistical analysis of the converter component losses produced to assess their suitability for wide output voltage applications. The dynamic performance of the converters is also evaluated to determine their stability for on-the-fly variations in output voltage. The analysis finds the three-level converter is the most efficient, however it suffers from slow dynamic performance.
