Due to the low voltage and high randomness of renewable energy, high-performance grid-connected converters are needed. With the advantages of a high boost ratio, flexible design, and simple control, the Y-Source Converter (YSC) is widely concerned. However, there are a few drawbacks to the traditional Y-source converter, including significant switching stress, voltage voltage overshoot, and discontinuous current. To solve the problems above, a series of improved topologies are proposed. Moreover, the voltage gain, current ripple, and soft switching characteristics have also been optimized. So far, the existing literature lacks the collation and comparison of different topologies of Y-source, as well as the analysis of its evolution process. Therefore, this paper provides a comprehensive overview of Y-source converters’ topologies. According to their features and applications, different topologies are classified and described, leading to guidance for the selection of YSCs under different scenarios. Meanwhile, the working principle, evolution process, and vital issues are analyzed. By revealing their deductive rules, valuable suggestions are provided for the future development of YSCs.

“…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.…”

A Comprehensive Small-Signal Model Formulation and Analysis for the Quasi-Y Impedance-Source Inverter

et al. 2023

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.

“…However, additional components in the network only serve to suppress spikes and improve device characteristics, not to increase the output voltage. To further increase the gain, a four-winding impedance network is used, which makes the design of the coupled inductor more difficult, the restrictive conditions of the turn ratio relationship are strict, and the adjustment flexibility is poor [39].…”

This paper proposes a single-switch integrated Sepic converter with a Y-source coupled inductor. The three-winding coupled inductor has higher voltage regulation efficiency, and the three-port tap of the y-source is easier to integrate with other structures to form a composite power cell. While ensuring the continuous input current, it can flexibly adjust the voltage gain, increase the power capacity, and reduce the voltage stress of the switch. The diode-capacitor branch in the integrated topology is used as a clamp to suppress the voltage shock while using the absorbed leakage energy to achieve soft-switching characteristics, mitigate diode reverse recovery, and improve the efficiency of the converter. The converter can be applied to the output of the photovoltaic (PV) array, a detailed theoretical analysis of the converter is carried out, and the general extension of the topology and the extension of the converter family are given. Finally, a 150 W prototype was built to verify that the converter can achieve high gain under high efficiency.
