“…This oscillation is natural and the control system can only fix its mean value forced by the set point. The simulation shows well as vanishing the delivered reactive power, the DC link voltage oscillation decreases with benefit for both the input and the grid current that exhibit a lower distortion as evident from Figures 16,17,18,19,and 20. It is worthwhile to remark that for avoiding overmodulation, the fault tolerant converter has a DC link voltage 25-30% greater than that of a traditional grid converter.…”

Distributed generation (DG) is deeply changing the existing distribution networks which become very sophisticated and complex incorporating both active and passive equipment. The simplification of their management can be obtained assuming a structure with small networks, namely, microgrids, reproducing, in a smaller scale, the structure of large networks including production, transmission, and distribution of the electrical energy. Power converters in distributed generation systems carry on some different ancillary functions as, for example, grid synchronization, islanding detection, fault ride through, and so on. In view of an optimal utilization of the generated electrical power, fault tolerant operation is to be considered as a suitable ancillary function for the next future. This paper presents a complete modeling of fault tolerant inverters able to simulate the main fault type occurrence and a control algorithm for fault tolerant converters suitable for microgrids. After the model description, formulated in terms of healthy device and leg binary variables, and the illustration of the fault tolerant control strategy, the paper shows how the control preserves power quality when the converter works in the linear range. The effectiveness of the proposed approach and control is shown through computer simulations and experimental results.

“…Moreover, these switching state combinations differ from application to application. When a three phase bridge is used to drive an induction machine, the state of a switch in a leg will usually be the inverse of the state of the other switch in the same leg [1]. On the other hand, to drive a BLDC motor it is common to leave both switches of one leg open [5].…”
