Three-level ANPC topology energy storage converter dead zone realization system and method

The invention relates to the technical field of power electronics, in particular to a three-level ANPC topology energy storage converter dead zone implementation system which comprises a three-level ANPC topology power circuit, a core controller and a PWM controller. The three-level ANPC topology power circuit comprises twelve semiconductor devices; the PWM controller comprises four signal edge delay modules and a power device driving signal module; in the invention, the influence of a dead zone on the output positive/negative level width during and after the switching of the operation working conditions of rectification, inversion and reactive output can be compensated, the consistency of the level width and delay before and after the switching of various working conditions is ensured, and the electric energy quality of grid-connected current is optimized; and the turn-on and turn-off sequence and the dead time of all the switching tubes are always kept consistent and are not changed along with the change of
