Abstract

The method of energy feedback by using SVPWM control algorithm for three-level inverter is proposed. So how to apply SVPWM for three-level into inverter is analyzed. How to calculate the dwell time of voltage vector and how to know region of preference vector by using the judgment on two-level are acquired. Then achievement of PWM sequence is analyzed, and some PWM sequences are mended in order to reduce the total harmonics distortion of inverter output. At last, the experiment of energy feedback system based on SVPWM for three-level inverter is achieved. The result demonstrates that this project is correct.
