  • Method and apparatus for controlling modes of inverter circuit, and inverter
    Patent number: 11411488
    Abstract: A method and apparatus for controlling a neutral point clamped inverter circuit, and a neutral point clamped inverter. It is detected that whether the inverter circuit operates in an abnormal state. In a case that the inverter circuit operates in the abnormal state, a control mode of the inverter circuit is changed to a specified control mode in which a transistor that may be damaged is in an off state. In this way, there is not current flowing through the transistor, avoiding damage of the transistor and thereby improving safety of the inverter circuit.
    Type: Grant
