This paper presents a survey of the main publications and general design requirements and problems of inductive power transfer systems for dynamic charging of electric vehicles (EVs). The main different roadbed geometries, based on a single transmitter track and segmented transmitter coil array have been discussed. Different case studies considering charging scenario, vehicle speeds, power levels and transmitting and receiving coils geometry have been conducted. Some problems about the design of charging station and EV side control system and energy management system have been analysed. A prototype of a charging station has been developed and built to supply inductive power transfer system which delivers 10-35 kW power at an air gap between transmitting and receiving parts of 75-100 mm and horizontal misalignment of +/- 200 mm. The results have shown that the system can transfer the specified electrical power at efficiency of about 82-92% and that the inductive power transfer module and its dynamic matching during charging, exhibited high degree of stability under a misaligned (x-y-z) condition and battery state of charge.
