基于简化三电平SVPWM的T型三电平整流器控制研究
Control Strategy Research on T Three-level Rectifier with Simplified Three-level SVPWM
摘要
Abstract
In view of the problem that the traditional three-level space vector modulation(SVM)requires a large calculation of partitioning and voltage vector,a simplified three-level SVPWM strategy was presented,then,the digital implementation method of the proposed modulation was given. To improve the neutral voltage unbalance inherent problems of three-level T-type rectifier,neutral voltage balance control method based on the small vector modified was adopted. To test and verify the correctness of the neutral voltage balance control and the validity of the simplified SVPWM modulation method,a 5 kW T-type three-level rectifier prototype platform was built. The experiment results show that the proposed method effectively simplifiy the calculation of space vector modulation vector operation and the neutral voltage is kept balance.关键词
