Abstract
A method for operating a phase-leg of a three-level active neutral point clamped (3L-ANPC) converter is presented. The phase-leg includes an output terminal, a plurality of input terminals, and a plurality of switches disposed therebetween. The method includes operating the phase-leg in a neutral state to generate an output voltage having a neutral level. The method further includes transitioning the phase-leg to a first intermediate neutral state from the neutral state. Moreover, the method includes transitioning the phase-leg from the first intermediate neutral state to a first state to generate the output voltage having a first level. A modulator for operating the phase-leg of the 3L-ANPC converter is also presented. Moreover, a 3L-ANPC converter including the modulator is presented.
