Summary:Space vector PWM principle of neutral point clamped (Neutral Point Clamped, referred NPC) three-level inverter is introduced in this paper to propose three-level NPC inverter vector control method of a new switching vector graph. Based on the new switch vector diagram, it requires only a simple arithmetic to determine vector in which the role of the reference voltage range and output voltage space vector corresponding to the duration of action of the switching device solves the traditional method's shortcomings. The simulation is taken based on MATLAB. The results verify the correctness and validity of the method.
