Abstract ：
With the continuous expansion of wireless power transfer (WPT) in the field of electric vehicles (EVs) and automated guided vehicles (AGVs), there is a need for a wireless charger that can complete the charging of these two devices in a limited space. To fill the gap in this field, this paper proposes an integrated wireless transmitter (IWT) that is suitable for EV and AGV wireless charging under different frequencies, which can realize the radio energy transmission of two types of vehicles in one charging position. It can also tolerate different coupling structures in EV wireless charging, namely the unipolar (Q) and bipolar (DD) coils. The IWT is established by stacking the Q coil and the DD coil composed of two self-decoupled poles, combined with circuit configuration topologies. An experimental prototype is established to verify the interoperability performance. The proposed WPT system can achieve interoperability with EV wireless charging of Q or DD receiving coils at 85 kHz and AGV wireless charging at 200 kHz. © 2025 John Wiley & Sons Ltd.

Abstract ：
In the wireless power transfer (WPT) system of electric vehicles (EV), the interoperability and misalignment of the coupling structure will lead to the reduction of charging efficiency. To solve the above problems, this paper proposes a novel receiver (Rx). The proposed structure superimposes a unipolar (Q) coil with a cross-shaped solenoid, thereby forming three magnetic field directions in the vertical direction, which is used to achieve interoperability and misalignment tolerance characteristics with Q and bipolar (DD) coils. By combining the proposed structure with the topological structure, the corresponding equivalent mutual inductance is formed. Subsequently, the interoperability performance and misalignment tolerance of the proposed structure were verified by building the corresponding experimental prototype. The experimental results show that for the Q coil, the output voltage fluctuation is 18.14%, while for the DD coil, the output voltage fluctuation in the y-axis is 21.69%. © 2025 John Wiley & Sons Ltd.

Abstract ：
With the development of electric vehicles (EVs), lithium-ion batteries have two rated voltages: 400 and 800 V, and are suitable for different output power scenarios. Considering the interoperability of public wireless power transfer (WPT) facilities, the WPT system for EVs not only needs to be compatible with the battery voltage class (BVC) under the premise of meeting the corresponding output power level, but also needs to take into account different coupling structures, namely unipolar (Q) and bipolar (DD) coils. Under the background of the interoperability of the above-mentioned BVC and coupling structures, an integrated dual-decoupled transmitter is proposed. First, finite element analysis and optimization were carried out for the proposed coupling structure. While obtaining the optimal coil parameters, the interoperability performance with Q and DD coils was also achieved. Then, by combining circuit topology, four different output modes can be achieved, which are used to adapt to the BVCs under different power levels and different coupling structures. A downscaled experimental prototype with the power of 5.0-kW was established. Under the premise of 200 V input voltage, the efficient transmission of 200 and 400 V output of Q and DD coil was achieved. The dc-dc efficiency is greater than 91%. Finally, on the premise of meeting the interoperability of Q and DD coils, the proposed structure also has a certain degree of antimisalignment characteristics.

Abstract ：
The power supply issue for electrical devices in harsh and dangerous environments is challenging. This letter proposes a power supply solution using drones as an energy carrier to charge such devices. The drone is wirelessly charged at the ground-side station and then flies to the target place to charge the devices wirelessly. To achieve a compact and lightweight structure, the helical coupler is designed without compensation components and ferrite on the drone side. Thus, a drone-side uncompensated bidirectional wireless charging system is formed. Compensation capacitors and inductors are employed on the ground side to achieve zero phase angle. The antioffset performance and the constant-voltage output characteristic of the system are investigated. The experimental results verified that the proposed approach can be a competitive solution for charging devices in inaccessible places.

Abstract ：
Improving power density and system integration is a pivotal focus for wireless power transfer (WPT) in portable devices. However, challenges, such as misalignment tolerance and power fluctuation persist. This letter introduces a robust solution utilizing secondary independent PWM control. A coil structure combining solenoids and reverse windings ensures passive misalignment tolerance, while a grooved magnetic core integrates the converter, optimizing compactness. In addition, the secondary PWM control achieves precise output voltage regulation without communication. A high-power-density WPT prototype validates the proposed coupler and control method, demonstrating less than 1% output voltage fluctuation under a 50% misalignment and maintaining over 89% efficiency at 100 W. The secondary device is highly compact, measuring only 60 mm x 30 mm x 7.5 mm and achieving power density of 7.41 W/cm(3).

Abstract ：
In the medium- and high-capacity power applications, typically multiple switches connected in series and parallel are used in power electronic converters to handle high voltages and currents. Powering the driving circuits and auxiliary units with high insulation requirements is challenging. This article proposes a modular multioutput wireless power transfer system with constant-current (CC) output characteristics for auxiliary power supply. Compared with conventional solutions, there is no need for complex control circuits and much magnetic material. The dual-frequency topology with CC outputs is derived by applying the analytical method that used to obtain the dual-frequency topology with constant-voltage (CV) outputs. The conditions for the system to maintain zero phase angle at different frequencies are discussed. Lower output fluctuations than single-frequency multioutput systems and dual-frequency CV output systems are verified. A magnetic coupler with integrated compensation inductors is designed to eliminate the need for discrete inductors and improve the power density. An experimental prototype is built to verify the validity of the theory. The WPT system achieves an output current fluctuation of no more than 4.78%, a maximum system efficiency higher than 85%, and an output power of more than 10 W at a single port, which can well meet the requirements of auxiliary power supply.

Abstract ：
The traditional method for achieving misalignment tolerance using two detuned circuits depends on output sampling and communication between the primary and secondary sides. This article proposes a self-adaptive dual-channel detuned compensation topology to achieve a stable output for wireless charging of autonomous underwater vehicles (AUVs). In the low coupling coefficient interval, power is transferred through both channels; in the high coupling coefficient interval, power is transferred through only one channel. The mode switching process occurs naturally without additional switches or control. Two sets of arc-shaped coils are employed as the two channels, forming dual arc-shaped coil sets, without cross-coupling between them. Due to the symmetrical magnetic couplers, the mutual inductances of the two channels respond similarly to both rotational and axial misalignment. A 1.6-kW experimental prototype for the AUV wireless charging is built to validate the feasibility of the proposal. The output voltage fluctuation of the system is 8% within the coupling coefficient interval of [0.2, 0.6]. The system can still maintain over 89% transmission efficiency in the worst case.

Abstract ：
Research on wireless power transfer (WPT) systems, especially single-input multiple-output (SIMO) designs, has attracted significant interest due to their practicality. Nevertheless, existing multiple-output WPT systems face various challenges, including the inability to independently control the output levels at each port, reliance on specific decoupling coil structures, and poor space utilization. To address these issues, this paper introduces a novel compensation topology capable of achieving independently adjustable dual constant voltage (CV) outputs exploiting its inherent structural attributes. The proposed system employs fewer passive compensation components, thereby reducing its volume and cost. Furthermore, this design does not require complex closed-loop control strategies, simplifying the difficulty of controller design. Instead, it simply requires adjustments to the compensation component parameters to achieve the desired dual CV output levels, thereby ensuring system flexibility. Initially, a theoretical analysis is conducted, followed by simulation verification, and finally, an experimental prototype is constructed to validate the feasibility of the proposed system. © 1986-2012 IEEE.

Abstract ：
Power balancing topology is an effective solution to the photovoltaic power mismatch problem in a medium voltage dc system. However, the existing power balancing topologies are all based on a chain structure, in which the mismatched power needs to be transferred through multiple power balancing units (PBUs). In the case of severe power mismatch, the accumulated balancing power is very large, resulting in increased system power losses and current stress on the switches. To solve this problem, a circular power balancing topology is proposed in this article. By connecting another PBU between the first and last submodules of the modular converter, the power balancing path becomes circular. With this new structure adopted, there are two paths for power transfer between any two SMs. An optimization method is also proposed to reduce the current stress by half. Compared with an existing scheme, the proposed topology is able to improve the power efficiency. The theoretical analysis is verified by simulation and experiment. © 2025 IEEE.
