The wireless power transfer (WPT) system based on dual‐coupled transmitters has been proved to be a good alternative for high‐power applications. However, the efficiency of the WPT system is various with different loads. An active rectifier (H‐bridge) is equipped in the secondary side to replace the passive rectifier (diode rectifier). By controlling the conduction angle and the output voltage of the active rectifier, the equivalent optimal load of the secondary side can be achieved. Owing to the equivalent optimal load, the WPT system with dual‐coupled transmitters can achieve optimising power efficiency. The experimental results agree well with the theoretical analysis. The results show the proposed efficiency optimising strategy is a good candidate for a WPT system with dual‐coupled transmitters.
