The existing auxiliary power supply technology of high-speed maglev trains based on sliding current or on-board energy storage has a certain impact on the carrying capacity of the train and has certain safety hazards. Capacitive power transfer (CPT) is a new type of power supply technology and may become a new option for auxiliary power supply of maglev trains. Aiming at the problem of insufficient power supply of the existing CPT technology, this paper proposes a CPT system with double transmitters and a single receiver. In the system, a 10-plates capacitive coupling interface is adopted and a simplified equivalent circuit construction method is proposed. An LCLC and LC compensation networks are used on the primary and secondary sides respectively. The characteristics of the compensation network are analyzed and the design method of key parameters is given. An experimental prototype is constructed, and the results verify that the compensation network design method can ensure the system works in resonance and the system has a power superposition effect.
