Optimization and Simulation of Elimination of Even Order Harmonics Based on SVPWM Vector Control

In order to eliminate the even harmonic vector control, the reasons causing even order harmonics are analyzed, and a novel SVPWM algorithm, which can eliminate the even harmonics and reduce the switching losses, is put forward. In the algorithm, the seven-stages-switch order is replaced by the five-stages-switch order to reduce the number of order switch. As a result, the switch loss is reduced, and even order harmonics is eliminated as well. The simulation testing is carried out by using Matlab/Simulink. The experimental results show that the algorithm is valid and feasible.
