Title: Flexibility of wireless power transfer charging station using dynamic matching and power supply with energy dosing (Open Access)
Keywords: wireless power transfer, charging station
Abstract: 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..
