Implementation and Verification of a 50kW Opportunity Wireless Charger Design

Inhalt:
This paper presents the hardware and control implementation of the primary side of an LCC-C SP-S (Series Parallel-Series) Inductive Power Transfer (IPT) system. The system is designed to provide variable power transfer up to 50kW without the need for communication by controlling a fixed current in the primary coil. The advantages of this approach include its simplicity in design and implementation, optimization and adaptability for new designs. Validation of the system's performance is conducted through a combination of simulations and experimental testing. Key aspects related to design and modeling, addressing critical considerations in the development process are also discussed.
