Abstract: To avoid the abrasion of the third rail supply system and the noise problem, as well as to decrease the weight and space of the secondary side, a CLLC-CL compensated capacitive power transfer（CPT） system was proposed for high-speed maglev trains. Compared to existing compensation topology, the proposed new topology can reduce the number and space of the elements on the secondary side. According to the structure of the maglev train, a coupling structure with 2 primary plates in the middle and 2 secondary plates on both two sides was adopted. A dynamic power supply prototype was built based on the CLLC-CL compensation topology, which transfers power through 35 mm air gap with a 13.35 pF coupling capacitor. It is shown that about 1.41 kW power is transferred with 350 V input voltage and a 150W load when the system is working with 1 MHz frequency. The DC-DC efficiency can reach 91.67%. The results indicate that the CPT dynamic power supply system with the proposed coupling structure has good transmittability and stability
