“…Especially when the WPT system is combined with the moving train, the power supply range can be greatly expanded. Inductive power transfer (IPT) and capacitive power transfer (CPT) are the two main ways to realize wireless power transfer 4–11 . Since the IPT system achieves wireless power transmission through magnetic field coupling between the transmitting coil and the receiving coil, there is significant eddy current loss in the IPT system in a multi‐metal environment, and the presence of inductive coils can make the system more cumbersome.…”

SummaryThis paper proposes a multi‐loads capacitive power transfer (CPT) system based on a single relay plate for railway monitoring systems. The proposed system can supply power wirelessly to the monitoring system on the trackside and train carriages simultaneously to eliminate traditional power cables connection and prevent frequent battery replacement. Unlike the traditional multiple loads CPT systems, the proposed system uses only one relay plate, which is more stable and uncomplicated considering the coupler installation space and moving dynamically in the railway system. The proposed system adopts a CL‐LCLC‐CL compensation network to achieve a load‐independent output. The limitation of the charging load quantity is given in detail considering the coupler voltage stress distribution. An experimental prototype with three loads is also built to verify the effectiveness of the proposed system. Experimental results show that the proposed system achieves wireless power transfer to multiple loads simultaneously with two loads on the receiver and one on the repeater side. The load‐independent property is also achieved when two loads are removed. The maximum experimental efficiency is about 87.13%.

“…The compensation network is introduced to the IPT system to compensate the reactive power and increase the power and efficiency. The SS compensation topology is widely used for its load-independent characteristic [21,22]. To achieve a more compact receiver, the compensation capacitor in the receiver side can be removed, which forms SN compensation topology.…”

Inductive power transfer (IPT) technology is widely used in autonomous underwater vehicles (AUVs) to achieve safety and flexibility. However, the eddy current loss (ECL) will be generated in the seawater due to the high-frequency alternating current in the transmitter and receiver. An underwater IPT system with a series-none (SN) compensation topology is proposed in this paper to achieve a compact receiver for AUVs and reduce the ECL. The analytical model of the IPT system is built to analyze its transfer performance. The phase difference between the transmitter and receiver current of the SN compensation topology is larger than 90° compared to that of the conventional series-series (SS) topology, which can significantly decrease the magnitude of the electric field caused by coil currents; thus, the eddy current loss is reduced. Moreover, the optimal load resistance of the seawater IPT system is lower than that in the air, and the SN compensation topology has a more compact receiver with no compensation capacitor in the receiving side, which can save the internal space in the AUVs. An experimental prototype based on the SN topology is built, and the experimental results have verified the analysis.

SummaryRectifier load in inductive power transfer system has nonlinear characteristics. However, the traditional analysis method equates it to a pure resistor, which leads to a certain deviation between the theoretical analysis and the actual circuit. This will reduce the accuracy of the inductive power transfer (IPT) system model and affect the soft switching operation of the inverter. In this paper, the IPT system with S‐type topology on the secondary side is studied. Firstly, the resistance–inductance characteristics of the rectifier load are analyzed by simulation, and then a second‐order circuit response model is established to solve the time‐domain expression of voltage and current. Then, the fundamental component of voltage and current is extracted by Fourier transform to calculate the impedance value of the rectifier load, and the mathematical calculation model of the rectifier load is established. On this basis, the influence of the inductive component of the rectifier load on the input impedance of the IPT system is analyzed. Then, a parameter design method for zero voltage switching is proposed for S‐S and LCC‐S topologies. Finally, an experimental platform of S‐S and LCC‐S IPT system is built. The correctness and effectiveness of the theoretical analysis and the proposed parameter design method are verified by experiments.
