Flexibility of Wireless Power Transfer Charging Station Using Dynamic Matching and Power Supply with Energy Dosing

The scientific and applied problems discussed in this paper are related to the development of a wireless charging station using an inductive power transfer (IPT) module power supply with energy dosing and dynamic matching. A computer simulation and an experimental study allowed the authors to define the ranges of the parameter variation of the equivalent load and to design the best matching so that maximum energy transfer is efficiency achieved. The proposed principle of energy control provides highly reliable and a flexible charging station even with a simplified system of automatic control and fault protection. A prototype charging station is developed and built to supply an inductive power transfer system that delivers 30–35 kW power over an air gap between transmitting and receiving parts measuring 50–200 mm and with a horizontal misalignment of ±200 mm. The results showed that the system can transfer the specified electrical power with about 82–92% efficiency and that the IPT module and its dynamic matching during charging exhibited a high degree of stability under a misaligned (x-y-z) condition and battery state of charge.

Inductive Power

Inductive power transfer systems (IPTSs) systems are equipped with compensation networks that resonate at the supply frequency with the inductance of the transmitting and receiving coils to both maximize the power transfer efficiency and reduce the IPTS power sizing. If the network and coil parameters differ from the designed values, the resonance frequencies deviate from the supply frequency, thus reducing the IPTS efficiency. To cope with this issue, two methods of tuning the IPTS supply frequency are presented and discussed. One method is aimed at making resonant the impedance seen by the IPTS power supply, the other one at making resonant the impedance of the receiving stage. The paper closes by implementing the first method in an experimental setup and by testing its tuning capabilities on a prototypal IPTS used for charging the battery of an electric vehicle.

AbstractSubsea inductive power transfer is one of the reliable and efficient methods for limited electric power transfer between closely located subsea systems. A planar coiled system is modeled using the electromagnetic finite element analysis software MagNet, and the simulation results are compared with those of a developed prototype; it is found that 75‐125 kHz is the optimum frequency for electrical power transfer in sea water conditions. The power transfer performance for various water gaps and offsets is identified. The results indicate that the power transfer efficiencies vary from 63.4% to 0.9% for water gaps ranging from 50 to 500 mm at an operating frequency of 125 kHz. The model is also extrapolated to flux concentrated designs, and the coil dimensions required for higher power transfer applications are identified.
