This paper deals with reconfigurable control associated with switch failure fault tolerant converter topology for Wind Energy Conversion Systems (WECS). A typical WECS with Doubly Fed Induction Generator (DFIG) is concerned. A converter topology without any redundancy is studied. This fault tolerant topology becomes a ldquofive-legrdquo structure after switch failure detection and converter reconfiguration. Consequently, the same control strategy can no more be applied after fault occurrence and a ldquofive-legrdquo control strategy is proposed. The validation of the reconfigurable digital controller for the studied WECS with DFIG topology has been performed using a Hardware-in-the-Loop (HIL) reconfigurable platform including a Field Programmable Gate Array (FPGA) chip. ldquoFPGA in the looprdquo results are presented to show simultaneously the viability of the studied converter topology and of the reconfigurable control.
