The increasing electrification of buses and trucks necessitates a thorough review of the charging infrastructure. In this context, Wireless Power Transfer (WPT) systems using inductively coupled coils present a promising solution. However, the high power required for large battery capacities poses particular challenges for these systems, including high electrical loads for the system components as well as efficiency and scalability concerns. This paper discusses the development and operation of a 200kW WPT system that employs a single pair of coupled coils, along with multiple inverters and rectifiers. The concept, design, and development of a High Power WPT (HPWPT) system are presented, as well as its implementation. The system has been successfully tested, achieving an output power of 203kW with an efficiency of 95.2\%.
