【 摘 要 】

Four-leg matrix converter (MC) is an AC–AC converter which has the ability to drive the unbalanced load. It can be used in many fields such as the ice protection system of More Electrical Aircraft to reach a considerably high power density. Detailed space-vector modulation algorithm and circuit modelling are discussed in this study. Analysis, modelling, and characteristics of common-mode voltage (CMV) are presented. The relationship between the peak value of CMV and circuit parameters is studied and quantitative results are provided. Simulation of a four-leg MC driving system is built and an experimental platform based on DSP/CPLD control system is set up.
