Planar contactless battery charging platform is an emerging technology that has the potential of unifying the charging protocols of portable consumer electronic products. In this paper, a new hybrid structure which consists of a coil and a spiral winding is proposed for improving the uniform magnetic field distribution over the charging surface. An analysis into an optimal design of the number of turns and the dimension of the spiral winding is presented for a given concentrated coil. The uniform magnetic field distribution of the designed prototype is measured by an EMC scanner and by an energy-receiving coil. Based on circuit modeling and analysis, the inverter circuit topology and particularly the resonant compensation tank is designed for maximizing power transfer for multi-load applications. A design procedure is proposed and verified by the experiments. An efficiency of about 80% has been achieved for the coupling structure itself when four loads are charged on the platform simultaneously.

“…In [13], electromagnetic aspects of the coreless PCB transformers are proposed and lead to the conclusion that this technical solution is suitable for severe EMI environments. It is a reason why it has been widely developed during the last 15 years [2, [14][15][16][17][18][19][20][21][22][23]. The other reasons are the reliability and cost impacts on the industrial process of the PCB systems.…”

International audienceIn this study, a signal impulse transmission function is investigated which provides high insulation voltage capabilities for IGBT drivers devices. This electrical insulation is achieved with a printed circuit board (PCB) and classical copper windings. Two ferrite cores are added to improve the magnetic coupling effect and thus decrease the impulse current maximum value in the primary side. The electronic circuit involves a series resonant topology in the primary side and a parallel one in the secondary side. The classical electronic components lead potentially to cost-effective solutions. However, so as to optimise the proposed system, a design methodology based on virtual prototyping tools is carried out. The simulation results presented on a Pareto front are analysed with the help of propagation delay and average power consumption. Moreover, measurement results with a 1.6 mm PCB are compared with simulation ones. Finally, the proposed solution and the methodology design are clearly accurate and suitable for power electronic designers and especially for IGBT driver devices designers

“…In these applications, the transformer primary and secondary windings are physically separated by a distance that is usually much less then the dimensions of the cores/coils [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The existence of a non negligible distance between the primary and the secondary produces, in most cases, the increase of the leakage inductors and the reduction of the magnetizing inductance, resulting in a loosely coupled power transformer with low coupling coefficient.…”

This paper presents the analysis and design of a DC-DC series resonant power converter used as a contactless battery charger (5V DC − 1A) for a mobile electronic device. The system is enclosed in a sealed spherical shell containing temperature and humidity wireless sensors and related electronic circuitry for real time composting process monitoring.Some particular characteristics of the device and its physical dimensions impose a maximum distance between the primary and the secondary transformer windings of 20mm. For transformer type core and windings configuration selection criteria, an experimental characterization of loosely coupled power transformers was evaluated.Both simulation and experimental results, obtained in a 150kHz laboratory prototype, were used as evidence of the developed theoretical models and analysis.
