Three-port dc-dc converters (TPCs) integrate renewable energy systems, energy storage systems, and loads, which have the characteristics of high integration and high reliability. This article proposes a high-gain TPC with soft-switching for renewable energy system applications. In various operating modes of the proposed converter, all switches can achieve zero voltage switching turn-ON and all diodes can achieve zero current switching turn-OFF, which can effectively improve the efficiency of the converter. In addition, the coupled inductor achieves zero dc bias, which can reduce the magnetic size and core loss.

Abstract ：
With the development of electric vehicles (EVs), there are two rated voltage levels for lithium-ion batteries, namely 400 and 800 V. Given the interoperability performance of public wireless power transfer (WPT) facilities, EV WPT systems should efficiently transmit power for both battery options. In this letter, a method is proposed by combining the coupling structure with a reconfigurable inductor-capacitor-capacitor (LCC) compensation network to enable charging EVs with the nominal battery voltage (NBV) of 400 or 800 V at the same power level, while maintaining high efficiency. The secondary LCC compensation is reconfigured so that the equivalent compensating inductance is varied. The mathematical model is established. The downscaled experimental prototype achieves a dc-dc efficiency of 95.34 and 92.40% for the output voltages of 200 and 400 V at the power level of 1.5 kW, respectively. The feasibility of the proposed system has been verified under the condition of alignment and misalignment of two sets of coupling coils.

Abstract ：
The rapidly developing electric vehicles (EVs) calls for improvement in the charging system for the high-voltage (HV) and low-voltage (LV) batteries in EVs. In the conventional EV charger, wireless power transfer (WPT), onboard charger (OBC), and auxiliary power module (APM) are three separate structures. This article proposes an integrated charger for WPT, OBC, and APM by sharing power conversion stages with the advantages of cost effectiveness and high-power density. The transformer of OBC can be seen as two strongly coupled coils, and the secondary-side coil can be loosely coupled with the transmitting coil of the WPT system, serving as a receiving coil. A transformer can be employed on the receiving side to integrate the APM with WPT. In this way, the receiving coil, the compensation network, and the power electronics converter can be shared. The integrated structure can work in three modes. In the first mode (wireless charging mode) and the second mode (conductive charging mode), the utility delivers power to the HV and LV batteries simultaneously. In the third mode (HV-LV mode), the LV battery is charged by the HV battery through APM. An experimental prototype is implemented to validate the proposal.

Abstract ：
A novel passive current sharing method for a multiphase wireless power transfer (WPT) system is proposed in this letter. For an N-phase inverter, there would be N compensating inductors in the inductor-capacitor-capacitor series (LCC-S) compensated WPT system. The proposed scheme introduces N external parallel resonant branches coupled with these N compensating inductors. In this way, an extremely large impedance is introduced in each loop of the circulating currents so as to balance the phase currents. No additional passive components with the rated power level are added to the power transfer channel. The proposed method employs two coupled inductors, which is easy to realize. Two new integrated structures for coupled inductors are introduced. The mathematical model and the current sharing principle of the proposed method are analyzed in detail. A 1.6-kW LCC-S compensated WPT experimental prototype with a four-phase inverter and the experimental results verify the effectiveness of the proposed current sharing method.

Abstract ：
Dynamic wireless power transmission (DWPT) is a promising technology as it reduces the battery capacity carried by automated guided vehicles and lowers its cost and weight. However, there are large mutual inductance and power fluctuation in the dynamic charging process. In order to solve this problem, this letter proposes a low-cost and low-fluctuation dual-receiver magnetic coupler, which is connected in parallel by two half-bridge rectifiers. The transmitter employs an I-type solenoid coil to enhance the magnetic field and improve the coupling. The optimized design of the coupler structure enables the system to have smooth mutual inductance fluctuation by switching the two receiving coils with each other during the dynamic charging process. The experimental results show that the measured equivalent mutual inductance fluctuation is 3.6%, which verifies the feasibility of the optimized design of the magnetic coupling structure and the effectiveness of the proposed DWPT system.

Abstract ：
In wireless power transfer (WPT) systems for electric vehicles (EVs), interoperability and misalignment tolerance for different receiving charging terminals meet great demands. In this article, a hybrid topology with a vector synthesis strategy and highly integrated magnetic couplers are proposed to achieve misalignment tolerance and interoperability for unipolar (Q), bipolar (DD), and quadrupolar (QUA) coils over the X and Y misalignments. By adjusting the phase angles of the four half-bridge inverters under different misalignments, the output voltage fluctuation can be limited. The mathematical model of the proposed hybrid topology is established and the vector synthesis strategy is introduced. The magnetic couplers and the design principle are presented. A 2-kW prototype is built to verify the proposed system. The experimental results demonstrate that the output voltage fluctuation under misalignments is less than 3.1% for the Rx Q coil, 3.3% for the Rx DD coil, and 4.3% for the Rx QUA coil, and the peak efficiency is 89.3%.

Abstract ：
A Y-source coupled inductor-based high voltage gain dc-dc converter with zero input current ripple (ZICR) is proposed in this article. ZICR is achieved by adding an auxiliary circuit which is composed of an inductor, a capacitor, and a coupled inductor in series. The presence of the capacitor results in an average zero current passing through the ZICR structure. Therefore, a small size magnetic core can be used to design the inductor, which can reduce the volume and copper loss of the magnetic components. In addition, a Y-source coupled inductor along with a voltage multiplier is used to achieve high voltage. The inherent passive clamp circuit effectively restricts the off-voltage spike and voltage stress across the switch. By utilizing capacitors to absorb the leakage energy, zero current switching (ZCS) turn-off of all diodes is achieved and mitigates the reverse-recovery issues of the converter. A 200 W 32-380 V 50 kHz experimental prototype is built to verify the feasibility of this converter. Within the output power range of 40-200 W, the efficiency of the prototype with the ZICR structure is higher than that without this structure. The maximum efficiency of the converter with the ZICR structure and without it are 95.9% and 95.6%, respectively.

Abstract ：
In industrial applications, multiple devices operate concurrently and require simultaneous power supply. Due to reliability requirements, isolated voltage sources with multiple independent outputs are preferred. This paper proposed a non-overlapping self-decoupling structure for wireless power transfer (WPT). The coil is divided into two parts that are positively and negatively coupled to other coils. The inductor-capacitor-capacitor series (LCC-S) topology is used to realize constant voltage (CV) outputs. A flowchart of the coupler design is given and an experimental prototype is constructed to verify the feasibility of the proposed system. The system can achieve CV outputs of 112 V, 93 V, and 83 V respectively, with a maximum variation rate of 1.05%. IEEE

Abstract ：
Dynamic wireless power transfer (DWPT) for electrical vehicle (EVs) is a promising technology that can alleviate mileage anxiety and address on-board battery capacity limitations. However, there are power fluctuation and interoperability problems in DWPT systems. In order to solve these two issues, this paper proposes a decoupling self-adaptive two-pole interoperable receiver. The receiver coils are decoupled by partial overlapping. During the EV movement, the receiver coil can automatically change its polarity according to the mutual inductance variation. In this way, the secondary-side rectifier presents a series or parallel connection and produces a smooth equivalent mutual inductance fluctuation within the moving range, thus achieving a smooth output. Meanwhile, the proposed receiver can be tolerant with the unipolar and bipolar transmitter coils, capable of outputting the same power level and high transmission efficiency. The experimental results validate the effectiveness of the proposed DWPT system. IEEE

Abstract ：
The traditional arrangement to charge multiple electric vehicles (EVs) in an EV wireless charging station is to share a common dc bus for multiple inverters. To charge EVs with different power levels, the charging modules should be designed to be different, which will increase the cost and complexity. A modular design approach for a wireless charging station with a common ac bus is proposed in this paper. All the charging modules are paralleled on the ac side of the inverters through transformers, and each charging module can be designed to be the same and fully utilized through the proposed arrangement. A voltage regulation strategy based on the active rectifier is proposed. The output voltage and power can be adjusted through the control strategy. An experimental prototype with two modules and three charging ports is built and the operations with different output ports are carried out. The proposed system can charge multiple EVs, and the charging voltage of each port can be adjusted independently through the proposed control strategy. IEEE
