FPGA-based reconfigurable control for fault-tolerant back-to-back converter without redundancy.

Shahbazi, M. and Poure, P. and Saadate, S. and Zolghadri, M.R. (2013) 'FPGA-based reconfigurable control for fault-tolerant back-to-back converter without redundancy.', IEEE transactions on industrial electronics., 60 (8). pp. 3360-3371.


In this paper, an FPGA-based fault-tolerant back-to-back converter without redundancy is studied. Before fault occurrence, the fault-tolerant converter operates like a conventional back-to-back six-leg converter, and after the fault, it becomes a five-leg converter. Design, implementation, and experimental verification of an FPGA-based reconfigurable control strategy for this converter are discussed. This reconfigurable control strategy allows the continuous operation of the converter with minimum affection from a fault in one of the semiconductor switches. A very fast detection scheme is used to detect and locate the fault. Implementation of the fault detection and of the fully digital control schemes on a single FPGA is realized, based on a suited methodology for rapid prototyping. FPGA in loop and also experimental tests are carried out, and the results are presented. These results confirm the capability of the proposed reconfigurable control and fault-tolerant structure.
