Study of three-level SVPWM algorithm for 60° coordinate system

摘要

This paper aims to calculate the complex shortcomings of the space vector PWM in the right angle still coordinate system. The realization method of the SVPWM under the 60 degree coordinate system is described, and the simplified small area judgment method is used to reduce the complicated calculation, which making the calculation of the control method more refined. The study of three-level inverter SVPWM algorithm can improve the utilization rate of DC, whether it is for China's energy use or environmental protection has a very important significance.
