Abstract

This paper presents a novel fault tolerant converter topology for grid connected Wind Energy Conversion System (WECS) with Doubly Fed Induction Generator (DFIG). This topology allows fault detection and compensation of one of the semiconductors or drivers by using isolating and connecting devices. It is based on a unique redundant leg for both back to back converters. We present a new detection algorithm, robust to false fault detection due to semiconductor switching. Simulation results are presented for two open circuit cases on both back to back converters.
