一种用于Vienna整流器电流谐波抑制的零序分量注入调制方法

Owing to the operational characteristic of a Vienna rectifier, it is found that the traditional modulation method would result in the current distortion. This paper, therefore, proposes a novel zero-sequence component injection modulation method for improving the input quality of the Vienna rectifier with balanced or unbalanced dc-link voltages. In specific, the degree of unbalanced dc-link voltag...
