Fault-tolerant five-leg converter topology with FPGA-based reconfigurable control.

Shahbazi, M. and Poure, P. and Saadate, S. and Zolghadri, M.R. (2013) 'Fault-tolerant five-leg converter topology with FPGA-based reconfigurable control.', IEEE transactions on industrial electronics., 60 (6). pp. 2284-2294.

Abstract

Fast fault detection and reconfiguration of power converters is necessary in electrical drives to prevent further damage and to make the continuity of service possible. On the other hand, component minimized converters may provide the benefits of higher reliability and less volume and cost. In this paper, a new fault-tolerant converter topology is studied. This converter has five legs before the fault occurrence, and after fault detection the converter continues to function with four legs. A very fast fault detection and reconfiguration scheme is presented and studied. Simulations and experimental tests are performed to evaluate the structure requirements, the digital reconfigurable controller, and fault detection scheme. For experimental tests, the control and the fault detection and reconfiguration schemes are implemented on a single field-programmable gate array (FPGA) chip. Experimental and simulation results show the effectiveness of the proposed fault-tolerant topology and its FPGA-based control.
