N2 - This paper proposes a compact module of transmitting and receiving unit which has a shield part for capacitive coupling power transfer (CPT) system, and describes the analytical study of the shielded CPT structure with the simplest design approach. The Spice simulation results show the stability of shield voltage expressed by a constant zero voltage and the resonant inductance does not be affected by the change of coupling capacitance or the coupler distance. Power ratio of output over input, -0.8 dB or 83% at 10 cm couplers distance in the range of working frequency from 13.00 MHz to 13.57 MHz can be obtained with an experimental setup. The system can maintain the efficiency to the level 66% for tolerance 3 cm misalignment in Y-axis. With a 1 cm gap between the shield-plate and the coupler, it shows a thin and compact transmitting and receiving module.
