摘要

Summary the system of energy conversion; energy cell for use as a stage of energy in a multilevel inverter circuit; and method for diverting a stage of energy of a multilevel inverter circuit multilevel power converters (10), power cells (100) and methods (510) Are presented to divert selectively a stage of energy (100,400) of a multilevel inverter circuit (40), in which a simple relay or counter (500) comprises one or more connections to output control normally closed (cnc1, CNC2) coupled between a circuit switched cell energy and determined output energy cell, A bypass connection normally open (cno1) coupled to the output stage of energy.With a regulator of current local or central (200, 506) which energizes the coil (502) of the relay or counter (500) of a given cell to divert that cell (100). 1 / 1
