N2 - Multi-load wireless power transfer (WPT) using electromagnetic induction principle has attracted increasing attention recently. However, there is much difficulty to achieve targeted power distribution to multiple loads and stable transmission power with misalignment between sending coils and receiving coils. To solve this problem, as a representative case, this paper employs a two-phase magnetically coupled resonant (MCR) WPT system with two receiving coils. The receiving coils are adjusted at two different frequencies to implement load identification. Meanwhile, by adjusting the resonant frequency of sending coils, the targeted power distribution to selective loads is achieved. Furthermore, the system combines two orthogonal sending coils excited by two equivalent ac sources with phase-shifted angle control to stabilize the transmission power. Finally, a prototype is built to test the transmission power of the system and the experimental results are in agree with the theoretical analysis.
