用于多桥臂电机驱动系统的通用型脉宽调制策略
A generic PWM strategy for multi-leg VSI-fed machine drives
摘要
Abstract
A generic pulse width modulation(PWM)strategy is proposed for the multi-leg voltage source inverter(VSI).First,the multi-leg VSI is modeled,which is independent from the load structure.Secondly,the proposed PWM strategy is deduced by inverting the mathematical model of the multi-leg VSI.According to the relationship between the leg number of VSIs and the phase number of electrical machines,the multi-leg VSI-fed machine drives are classified into two types:matched and unmatched applications.The leg numbers of VSIs and the phase number of electrical machines are equal in matched applications while they are different in unmatched applications.The existing PWM strategies cannot be directly used for both matched and unmatched applications.However,the proposed PWM strategy can be general for both matched and unmatched applications,and no modifications are required.The effectiveness of the proposed PWM strategy is verified by experimental results.关键词
