Abstract
This disclosure describes systems, methods, and apparatus for reducing current imbalances between phases in a multi-phase converter as well as reducing instances of particular phases switching twice within a single pulse-width modulated cycle, or other time period. Phases that have not switched for a longest period of time can be compared to see if swapping their firing patterns would reduce current imbalances, and if so, then those firing patterns can be swapped.
