Patent Primary Examiner
A method for controlling shutdown wave blocking of a multilevel inverter circuit and an application apparatus for applying the method are provided. After a shutdown command is issued, the multilevel inverter circuit is controlled to switch between a free state and a specific turn-on state. The free state is a state in which all switch tubes in the multilevel inverter circuit are turned off. The specific turn-on state is a state in which voltage stress withstood by a switch tube, on which clamping protection is not performed, in the multilevel inverter circuit is zero by controlling a specific combination of switch tubes in the multilevel inverter circuit to be turned on.
