Abstract
Certain aspects of the present disclosure generally relate to techniques for operating a three-level buck converter. An example method for operating the three-level buck converter may include: identifying a voltage value based on an input voltage of the three-level buck converter; determining an emulated current for an inductive element of the three-level buck converter based on an expression having a variable associated with a voltage across a flying capacitive element of the three-level buck converter, wherein determining the emulated current comprises assuming the variable to have the voltage value; comparing the emulated current to a threshold; and controlling at least one transistor of the three-level buck converter based on the comparison.
