A novel method of suppressing inrush currents of squirrel-cage induction machine using matrix converter in wind power generation systems

This paper proposes a novel method of suppressing inrush currents of squirrel-cage induction machines using matrix converter in wind power generation systems. In the proposed method, the series-connected side of the matrix converter behaves as a resistor for the induction machine current. Digital computer simulation is implemented to confirm the validity and practicability of the proposed method using PSCAD/EMTDC. Simulation results demonstrate that the proposed inrush current suppressor can suppress the inrush current perfectly.
