Accurate modeling and multi-objective optimization of multi-transmitter multi-receiver WPT systems

This paper presents a novel modeling and design methodology for Multi-Transmitter Multi-Receiver (MTMR) Wireless Power Transfer (WPT) systems. A general mathematical model is introduced, capable of handling arbitrary system sizes and including parasitic components and cross-coupling effects through a mutual inductance matrix formulation. To optimize the resonance compensation network, a genetic algorithm-based design flow is adopted, targeting both output power matching and global efficiency, regardless of the number of transmitters and receivers. The effectiveness of the approach is validated through simulations and experimental results, showing high accuracy in power delivery and overall system performance.
