The DSWIG scheme proposed in this paper uses an inverter with apparent power lower than the corresponding generator power. The expected ratio between the inverter power and the generator power is 50% in the case of DSWIG. This is similar to DFIG applications. The advantage of DSWIG is the lack of brushes. DSWIG can be used in variable speed applica...
