DRIVING METHOD FOR 3-LEVEL NEUTRAL POINT CLAMPED INVERTER

摘要

A method for driving a 3-level neutral point clamped inverter according to the embodiment of the present invention includes a first step of repeating the on and off of a first IGBT when a second IGBT, a third IGBT, and a fourth IGBT are on, off, and on, respectively after the first step, a second step of repeating the on and off of the second IGBT when the first IGBT, the third IGBT, and the fourth IGBT are off, a third step of repeating the on and off of the fourth IGBT when the first IGBT, the second IGBT, and the third IGBT are off, off and on, respectively after the second step, and a fourth step of repeating the on and off of the third IGBT when the first IGBT, the second IGBT, and the fourth IGBT are off after the third step.
