Research of SVPWM Algorithm Based on Three-level Inverter

Three-level inverter is widely used because of its advantages in high power applications.Works of three-level inverter were analyzed,and SVPWM algorithm was applied in three-level inverter.The algorithm gives the role of rules what position reference vector is located in and the sequence of all vector works;the trouble of midpoint potential imbalance was existed in the main circuit,we can solve this problem though particular method that regulate the time of positive and negative small vector in inverter.Test results verify the algorithm in Matlab.
