Abstract ：
A capacitive wireless power transfer (CPT) system based on parity-time (PT) symmetry achieves constant output characteristics under distance variation without additionally increasing the system complexity of the control strategy, where the concept of PT symmetry is derived from quantum mechanics, and the systems satisfying PT symmetry are invariant under space and time inversion. However, the exact PT-symmetric region (i.e., strong coupling region) of the general system is limited by the symmetry of the structure and parameters. To overcome this limitation, a novel generalized parity-time (GPT)-symmetric CPT system is proposed in this article. According to the equivalent circuit method, the circuit model of the proposed system is built, and the transfer characteristics are analyzed. Furthermore, a prototype is implemented to verify the feasibility of the proposed CPT system. The results show that the PT-symmetric region is extended by 169.23% compared with the traditional PT-based CPT system, and a constant output power of 21.5 W is transferred with a constant transfer efficiency of 90%.

Abstract ：
Magnetic Coupling Wireless Power Transfer (MCWPT) technology has broad application prospects due to its high degree of freedom in energy exchange and unparalleled security. In recent years, various controllers have been added to WPT systems to improve energy transfer performance. Among them, the Dual-Side Control (DSC) approach, which employs Dual-Active Bridge (DAB) converters with simultaneous control of the transmitter and receiver, has made great progress. The DAB structure has a compromise between cost and complexity, and the DSC can bring a high enough degree of control freedom to the MCWPT system to easily achieve efficiency optimization and desired output characteristics. However, various DSC methods have different characteristics. Therefore, this paper reviews and summarizes the current research status of DSC methods based on the DAB converters in MCWPT systems. Wireless communication is one of the decisive factors in the design of a control strategy, which is categorized in this paper according to the main approaches used in all the papers. Various DSC strategies are described in detail and compared comprehensively according to the control variables and control objectives. This review will be highly beneficial to research entities and industry professionals as a ready reference for the control design in MCWPT.

Abstract ：
Pad misalignment is almost inevitable in most wireless power transfer (WPT) systems, which leads to system performance degradation due to the variation of system parameters. Based on S-S and P-S compensation topology, this paper proposes a compact WPT system with dual-coupled SP-S compensation with anti-offset characteristics. Two coaxially arranged, mutually decoupled, rounded square coils are used as the energy transmitting coils, which are coupled with a single square receiving coil to improve the anti-offset tolerance in the X and Y directions. In the process of receiving coil offset, the output of one transmitting coil loop is increased and the output of the other coil loop is reduced by resonance parameter configuration, so that the system output fluctuates gently with the offset of the receiving coil. The design method of the structural parameters of the square decoupling coil is put forward and the influence of shunt compensation capacitance on the offset resistance of output is also analyzed. An experimental platform is built to verify the feasibility of the proposed method and the anti-misalignment performance of the proposed WPT system. ©2024 Chin.Soc.for Elec.Eng.

Abstract ：
This paper proposes a distance-independent wireless charging system that achieves constant current (CC) and constant voltage (CV) output through utilization of a reconfigurable topology, capable of seamlessly switching between a two-coil and a three-coil configuration. In order to enhance output adjustability and improve the efficiency of the charging process, this system combines the advantages of fractional-order and integer-order resonant circuits. In the two-coil configuration, the output of the inverter on the transmitter side is modulated as that of a fractional-order capacitor. By analyzing frequency characteristics of the fractional-order circuit, a control strategy of variable fractional order is introduced to achieve CC output against variations of transfer distance based on a mutual inductance recognition method. After transitioning to the three-coil configuration, the system inherently achieves a CV output by operating the inverter at a fixed frequency and forming an integer-order resonant circuit. In addition, in both mentioned configurations, the full-bridge (FB) mode and half-bridge (HB) mode of the inverter are utilized to minimize switching losses and broaden the range of soft-switching operation, catering to various load conditions. Finally, an experimental prototype is built to achieve CC and CV output within a wide charging range.

Abstract ：
Capacitive power transfer (CPT) technique uses coupled metal plates for energy transmission, which has the advantages of negligible eddy-current loss and low weight. To achieve efficient power transfer, the CPT system often adopts circuit resonance and impedance compensation, which are generally realized by integer-order components, such as inductors and capacitors. However, it remains a fundamental challenge to create a CPT system whose transfer efficiency and output power are robust against the variation of resonant frequency and the coupled plates' relative position. Therefore, this article proposes a robust fractional-order autonomous CPT system containing a fractional-order inductor. Theoretical analysis shows that the transfer efficiency and output power of the proposed fractional-order CPT system are inherently robust not only to the variation of the coupled plates' relative position but also to the resonant frequency. In contrast, the transfer efficiency and output power of traditional integer-order CPT systems are sensitive to the resonant frequency. The available experimental results verify the effectiveness of the proposed system.

Abstract ：
This article proposed an autonomous wireless power transfer system with misalignment tolerance and improved control degree of freedom based on detuning control for battery charging, in which the outputs can be regulated continuously and smoothly without additional dc-dc converters while maintaining soft-switching or zero-phase-angle operation of the inverter. Theoretical analysis shows that constant current (CC) or constant voltage (CV) independent of coupling coefficient and load can be achieved without information exchange between transmitter and receiver, which eliminates wireless communication. Furthermore, when the detuning ratio is controlled to be constant, a transfer efficiency insensitive to the variation of the coupling coefficient can be obtained. A prototype with a 6-A charging current and a 36-V charging voltage is built to support the feasibility of the proposed method. Experimental results demonstrate that within the coupling coefficient range of 0.283-0.456, CC and CV with transfer efficiency greater than 91.5% can be achieved.

Abstract ：
Wireless power transfer (WPT) is an emerging technology that enables the wireless transfer of electrical energy from power supplies to electrical equipment. It has been widely used in electric vehicles, mobile phones, household appliances, medical devices, and other fields. However, the frequency splitting and bifurcation phenomena existing in WPT systems are the fundamental obstacles and challenges that affect the effective operation of WPT systems. In this paper, a method based on the fractional-order circuit is proposed to simultaneously suppress the frequency splitting and bifurcation phenomena by changing the order of fractional-order capacitor. By replacing the compensation capacitor in the transmitter of the traditional WPT system with a fractional-order capacitor, a fractional-order WPT system is formed. Then, using fractional calculus and circuit theory, the mathematical model of the proposed WPT system containing a fractional-order capacitor is established, and the frequency splitting and bifurcation phenomena are analyzed. The theoretical results show that the frequency splitting and bifurcation phenomena are suppressed only by adjusting the order of fractional-order capacitor, and the output power of the original resonant frequency is improved. Finally, the experimental prototype is implemented to validate the theoretical results.

Abstract ：
In wireless power transfer (WPT) systems, it is well known that the series-parallel (SP)-compensated topology is preferable for large load systems, like biomedical implants and consumer electronics, etc. However, it is a major challenge for practical SP-compensated WPT applications to obtain efficient and stable power transfer characteristics under the variations of coupling coefficient and resonant frequency. Therefore, based on fractional-order (FO) circuit theory, this paper proposes an SP-compensated FOWPT system with coupling independence and detuning insensitivity. Experimental results show that stable output power is maintained with a constant transfer efficiency in a wide load range, and when the resonant frequency of the receiver is detuned +/- 5%, the fluctuations of output power and transfer efficiency are less than 1%. The experiment validates the effectiveness of the proposed system.

Abstract ：
In this paper, using dual-frequency modulation (DFM) and phase synchronization method (PSM), a flexible and controllable wireless power transfer (WPT) system with soft switching based on parity-time (PT) symmetry is proposed for kitchen appliances. Here, the system outputs can be regulated by configuring the number ratio of two modulation pulses with different frequencies, without the need for extra DC-DC converters or changing the duty cycle of the inverter. Moreover, a control method for generating and arranging the hybrid frequencies pulse sequence is proposed based on PSM to satisfy the condition of PT symmetry. Theoretical analysis indicates that a controllable output power insensitive to the coupling coefficient can be acquired only by relying on a single-stage inverter while maintaining soft-switching or zero-voltage switching (ZVS) operation, thereby reducing power losses and improving system cost-effectiveness and integration. Furthermore, dual-side communication can be eliminated. The results of the experiment confirm that a controllable stable output power with a constant coil-coil efficiency of 95.8% and a peak DC-to-load efficiency of 93.8% can be maintained within a lateral tolerance range of 0-14 cm.
