This paper proposes an optimal driving algorithm for 50 [kW] wireless charging system with multi-coil pad to achieve high efficiency over a wide load range under SAE J2954 misalignment. Two driving strategies are considered, simultaneous driving where all phases are activated and selective driving where only well-coupled phases are activated. The target system employs a three-phase pad composed of DDP coils for phases A and B and a CP coil for phase C, together with a three-phase IPT converter that supports phase selection. Based on loss characteristics under varying load and alignment conditions, the multi-coil driving algorithm is derived to switch between the two strategies and to select the active A/B phase during selective operation. Finally proposed multi-coil driving algorithm is validated the feasibility and efficiency improvement through experiments on a 50 [kW] system.
