N2 - Robust performance under misalignment conditions is a fundamental yet difficult-to-achieve requirement in inductive power transfer (IPT) systems. In this paper, a novel plane misalignment-tolerant inductance power transfer (IPT) system based on rectangular distributed coupler (RDC). The rectangular distributed coupler combines four rectangular coils in a distributed design to form a transmitter (Tx) pad, while the receiver (Rx) side is configured with a simple rectangular pad for effectively capturing a constant magnetic coupling under plane misalignment. Unlike existing solutions that often rely on active control and closed-loop compensation, the proposed IPT system achieves misalignment tolerance inherently through its passive structural design. To validate the effectiveness and practicality of the proposed design, a 0.5 kW experimental prototype has been developed and tested. Experimental results demonstrate that the system maintains a wide range of plane misalignment tolerance.
