Abstract: The traditional single-receiver inductive power transfer (IPT) system has a sharp drop in output voltage and system efficiency under significant misalignment. To solve this problem, the double-solenoid quadrature pad (DSQP), consisting of a square quadrature coil and the double-solenoid coil, was proposed. The coil structure was combined with the clamp circuit to realize automatic switching between the two coils and stable output capacity with relatively high efficiency versus the large misalignment range. A buck converter was employed to precisely control output voltage without RF communication. The misalignment performance and the design method of the proposed DSQP were elaborated. Finally, a 500W prototype was constructed to verify the validity of the proposed method. The outer dimension of both the primary and the secondary side coils were 400mm × 400mm. The experimental results show that the dc output voltage can be maintained at 72V with 320mm (80%) misalignment. The DC-DC (including Buck) system efficiency is at least 87.4%, and the highest is 90.5%.
