—This paper presents a top–down design flow for design , implementation, and verification of digital controllers associated with electrical systems. In the proposed design flow, the functional description of the studied system and the detailed electronic hardware design and validation of the digital controller are performed using a hardware-in-the-loop(More)
—This paper discusses the design, implementation, experimental validation, and performances of a field-programmable gate array (FPGA)-based real-time power converter failure diagnosis for three-leg fault tolerant converter topologies used in wind energy conversion systems (WECSs). The developed approach minimizes the time interval between the fault(More)
Fast fault detection (FD) and reconfiguration is necessary for fault tolerant power electronic converters in safety critical applications to prevent further damage and to make the continuity of service possible. The aim of this study is to minimize the number of the used additional voltage sensors in a fault tolerant three-phase converter. In this paper,(More)
In this paper, a hybrid energy storage system was implemented using batteries and ultracapacitors. The goal of the research is to manage and to optimize energy flow from sources considering consumer demand. Ultracapacitors are requested during power demand, so batteries function under better conditions by avoiding deep discharges. Ultracapacitors role is(More)
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(More)
