Abstract
Dynamic inductive coupled power transfer (DICPT) is one of the most promising technologies for railway power supply where no catenary is available and light boarded energy storage system is desired. This paper presents the design and characterization of a DICPT system based on meander-type coils with different geometrical constraints. Constant coupling is demonstrated with a three-phase solution, simplifying dramatically the control stage. A small-scale prototype is built verifying the power transmission equations. Additionally, different resonance configurations are analyzed with the aim of designing the most efficient solution. Finally, electric equations are presented and a 60-kW DICPT system is designed.
