Abstract
Methods and apparatus are presented for controlling a power converter to protect input filter inductors from overheating, in which an active front end (AFE) rectifier is operated in a boost mode to provide a boosted DC voltage at a derated output current value selected according to the DC bus voltage boost amount corresponding to a maximum load condition for which the filter inductors will not overheat.
