“…Now, as reported in [31], the windings and currents of each coupled-inductor coil are related by (19). Applying KCL on the coupled-inductors, one can derive (20). Despite the fact that I C2 = I N1 + i m , considering a large enough magnetizing inductance L m , i m is comparatively lower than I N1 in steady state and hence during shoot-through I C2 ≈ I N1 .…”

“…Despite the fact that I C2 = I N1 + i m , considering a large enough magnetizing inductance L m , i m is comparatively lower than I N1 in steady state and hence during shoot-through I C2 ≈ I N1 . Therefore, by substituting (18) for (20), it is possible to derive expressions for I N3 and I N2 with respect to I N1 and I C2 , as can be seen in ( 20) and (21).…”

“…The impedance-source configurations based on the Y-source network are of particular interest as they can provide one of the highest voltage gains, lower component quantity, and smaller shoot-through periods [17]. Moreover, the research conducted with Y-source impedance networks recently that was carried out covers different aspects of this class of impedance-source converter, ranging from (a) the proposition of new topologies, to reduce input current ripple [18] and allow soft-switching [19], higher voltage boosting gains through switched inductors [20], or the intrinsic damping of DC-link voltage spikes due to leakage inductances [21,22] ; (b) the review of Y-source based magnetic-coupled impedance source networks [23,24]; (c) applications with renewable energy sources based on solar or wind-based generators [25,26] and (d) the proposition of model-predictive control approaches [27]. However, none of these recent publications performs a comprehensive analysis of its proposed Y-source-based converters, with small-signal modeling based on state-space averaging, considering a dynamic evaluation of the DC-link control under impedance-network components parametric variations.…”

This paper presents a detailed derivation of the small-signal model and components design considerations for the quasi-Y-source inverter. The design methodology is based on the converter steady-state operation, considering the impedance network inductor and capacitor voltage and charge balances, respectively. Moreover, the additional design criteria for component selection, considering control constraints and performance compromise, are given by parametric variation analysis based on converter dynamic response. The small-signal model and transfer functions are obtained using a state-space averaged model, including converter non-ideal characteristics given by equivalent-series resistances (ESR), which makes possible the proposition of different control strategies, using both single or multi-loop schemes. To demonstrate the usefulness of the proposed small-signal model, a DSP-based single-loop type-II PI control strategy is used in which the peak DC-link voltage is indirectly controlled through the measurement of the impedance network capacitor voltage. The controller and converter performances are verified with simulation and experimental results and successfully confirm the validity of the proposed dynamic model. Finally, the obtained results are validated with a built small-scale three-phase/three-wire inverter prototype.

Currently, many scholars have conducted relevant basic research studies on ECC materials.…”

The bending performance of polypropylene fiber reinforced engineered cementitious composite (PP-ECC) beams was studied. A total of five reinforced concrete (RC) beams were prepared and tested. The test variables include matrix type, longitudinal reinforcement diameter, and longitudinal reinforcement ratio. The study found that ECC is an ideal building material to improve the bending performance of RC beams. For the failure mode, even if the ultimate load is reached, no local cracks are observed in the ECC beam. On the contrary, due to the high ductility of the ECC material, multiple microcracks appear in the tension zone of the beam. From the perspective of bending performance, the use of ECC materials as the matrix of RC beams can not only increase the cracking load, yield load, and ultimate load of RC beams but also increase its ductility and energy absorption capacity. A method for predicting the flexural bearing capacity of ECC beams considering the effect of fiber tensile stress is proposed. The experimental data in this study are compared with the experimental data in the previous literature, and the prediction results of this model and other previous models are obtained. The average ratio of the predicted value of the flexural bearing capacity of the RC beam to the experimental value is 0.979, and the coefficient of variation is 0.016.
