“…In [38], SM control was designed for an SS-compensated WPT system to achieve maximum energy efficiency as well as output voltage regulation. The transmitter of the SS-compensated WPT consists of a full-bridge high-frequency DC/AC resonant inverter (S 1 to S 4 ) being controlled by a perturb-and-observation (P and O) phase-displacement control to minimize the input current from the renewable source, thereby achieving minimum input power.…”

“…The output of the receiver coil is connected to a full-bridge high-frequency rectifier diode circuit comprising D 1 to D 4 with storage capacitor C b . Controller 1 is a P and O phase-displacement control for achieving minimum input power of the variable renewable source via the regulation of the zero-state phase angle of the output voltage of the DC/AC inverter V in (schematics of Controller 1 can be found in [38]). Controller 2 is for regulating the output voltage the buck-boost converter and in this study, both the conventional PI control and the SM control are adopted for comparison.…”

“…In more recent works, the state-of-the-art research on SM control of renewable energy systems involve, in addition to achieving high power quality, the dynamic tracking improvement of the renewable energy systems. By far, several investigations have been carried out to showcase the advantages of SM control over linear control in dynamic power tracking of the systems with renewables [33][34][35][36][37][38][39]. In [35], a reduced-order SM controller was designed for a cascaded boost converter in a photovoltaic (PV) system to achieve a high conversion ratio with an efficiency of close to 95% for a wide operating range.…”

“…This is due to the fast-dynamic-tracking merit of SM control, which significantly improves dynamic energy-harvesting property as compared to linear controllers in conditions of variable sun and wind. In [38], a pulse-width-modulation (PWM)-based SM control was applied to the buck-boost regulator of the series-series (SS)-compensated wireless power transfer (WPT) system with variable power generations and consumptions. The PWM-based SM control exhibits better dynamic tracking performance of the output voltage than the conventional linear control when the input voltage, the mutual inductance, or the load condition of the WPT system is variable.…”

Based on the matured theoretical framework of sliding mode control for varied, nonlinear, and unpredictable systems, practical designs of sliding mode control have been developed to suit the purpose of controlling power converters under various operating conditions. These design guidelines are particularly valuable for emerging technologies with renewable energy sources. This paper presents a discussion on the recent development of sliding mode control applications for renewable energy systems, and further examines the current trends of achieving efficiency improvement of renewable energy systems and load protections against large overshoot/undershoot in transient states, by utilizing the fast-dynamic-tracking capability of the sliding mode control. Three comparative case studies between the sliding mode control and proportional-integral control involving, namely, a low-power wind energy conversion system, a series-series-compensated wireless power transfer system, and a multiple energy storage system in a direct current (DC) microgrid, are provided.

Uncertainty commonly exists in the wireless power transfer (WPT) systems for moving objects. To enhance the robustness of the WPT system to uncertain parameter variations, a modified WPT system structure and an interval-based uncertain optimization method are proposed in this paper. The modified WPT system, which includes two Q-type impedance matching networks, can switch between two different operating modes. The interval-based uncertain optimization method is used to improve the robustness of the modified WPT system: First, two interval-based objective functions (mean function and variance function) are defined to evaluate the average performance and the robustness of the system. A double-objective uncertain optimization model for the modified WPT system is built. Second, a bi-level nested optimization algorithm is proposed to find the Pareto optimal solutions of the proposed optimization model. The Pareto fronts are provided to illustrate the tradeoff between the two objectives, and the robust solutions are obtained. Experiments were carried out to verify the theoretical method. The results demonstrated that using the proposed method, the modified WPT system can achieve good robustness when the coupling coefficient, the operating frequency, the load resistance or the load reactance varies over a wide range.

Considering a prospect where a driverless electric vehicle (EV) requires an automatic charging system that does not need a person to do anything. In this case, there is a need for a fully automated, fast, safe, cost‐effective, and reliable charging infrastructure that can be used for EVs and other EVs. This infrastructure must also be profitable and allow for quick adoption in electric transportation systems. Wireless charging methods may allow you to understand these characteristics. Wireless power transfer (WPT) is a future technology that offers flexibility, convenience, safety, and the capacity to be automated. Due to its high efficiency and ease of maintenance, resonant inductive wireless charging should get more attention in WPT techniques than other WPT methods. This literature provides an overview of the status of Resonant Inductive Wireless Power Transfer Charging technology, as well as a look at the current and prospects of the wireless EV industry. First, the article provides a brief history of wireless charging technologies, outlining the benefits and drawbacks. Then, the research assists in a comparative analysis of various types of WPT methodologies, control strategies, and compensation networks that have been done so far. The static and dynamic charging procedures, as well as their features, are shown. To increase charging power, a novel approach to the usage of superconducting materials in coil designs is examined, and their potential influence on wireless charging is highlighted. The detailed role and importance of power electronics, as well as the many types of converters utilized in diverse applications, are highlighted. The batteries and their management systems, as well as numerous WPT difficulties, are also discussed. Different trades are investigated, including cyber security economic consequences, health and safety, foreign object identification, and the effect and influence on the distribution grid. This article also highlights the opportunities and challenges associated with wireless charging systems. We anticipate that our effort will contribute to the advancement of WPT system research and development.
