Abstract
Highly Resonant Power Transfer (HRPT) technology is currently receiving very significant attention from the industry and the smart power grid distribution community in particular. This technology ensures electrical power transmission between two points while controlling the level of transmitted power and ensures the immediate shutdown of the transmitted power in the event of a problem. This paper reviews the inductive power transfer method and describes the design of an ultra-compact PLA core electromagnetic coupler. The proposed architecture confines the magnetic field in a toroidal PLA core transformer, and by avoiding the use of heavy and bulky shielding plates, reduces magnetic losses and avoids the Curie point. As a result, the overall unit has a weight of 5 kg and a volume of only 0.013 m3. The electromagnetic coupler is capable of transferring a peak power of 150 kW with an operating frequency of 193 kHz, giving a satisfactory efficiency of 95%. The proposed novel system was first investigated through CST 3D numerical modelling to determine the electrical parameters of the coupler’s equivalent circuit and its efficiency, to verify its compatibility with the ICNIRP 2010 standard and to evaluate its temperature rise with an air-cooling system. Afterwards, the designed coupler was built with a 3D printing device and finally tested experimentally. Simulation and experimental results are compared and show a good agreement.
Highlights
In toroidal coupler, the winding occupies the full periphery of the core, resulting in reduced leakage inductance and stray electromagnetic field
It has advantages related to size and volume. It is widely used in low power applications but is still not very available in high power ones and less studied compared to the conventional transformer
The aim of this paper is to demonstrate that toroidal electromagnetic coupler can be used in modern high power applications, such as smart grid technology
Summary
The winding occupies the full periphery of the core, resulting in reduced leakage inductance and stray electromagnetic field. It has advantages related to size and volume. Thanks to those merits, it is widely used in low power applications but is still not very available in high power ones and less studied compared to the conventional transformer. One of the main components of this technology is the transformer, which must ensure efficient power transmission with high-performance control and communication systems. In this present, we will show the possibility of replacing a conventional transformer by a galvanically isolated PLA core toroidal electromagnetic coupler that will address the main challenges of smart grid technology using the inductive transmission method
