摘要
In order to well solve the problem of the output voltage unbalance, which is caused by unbalanced load of high frequency link matrix converter(MC), a kind of high frequency link three-phase four-leg MC has been proposed. Firstly, the root cause of the output voltage unbalance is analyzed. Then through building up the mathematical model of high frequency link three-phase four-leg MC, it is verified in theory that the de-re-couple control strategy is suitable for three-phase four-leg MC. Finally, closed-loop system suiting for a variety of unbalanced loads is simulated by MATLAB software based on the symmetrical component. The simulation results show that the high frequency link three-phase four-leg MC is a good solution to imbalanced output voltage.
