Abstract: This paper proposes an effective protection strategy which combines three-crowbar circuit configuration (TCCC), a small bypass resistor (SBR) for wind turbines (WTs) based on the doubly fed induction generators (DFIGs). The TCCC includes (i) resistive… read more here.

Abstract: Theoretically, the energy conversion efficiency of the synchronous induction coil launcher (SICL) can reach 100%, but at present, the test data show that the highest current is only a little higher than 20%, which shows… read more here.
