Abstract  

The compensation network of the inductive power transfer (IPT) system was separated and added to each parallel inverter to solve the power expansion and circulating current problems. Firstly, the mathematical models of the IPT system with single-inverter topology and power expansion topology were analyzed. Secondly, the compensation network parameters of each parallel inverter were designed, and the power and efficiency expressions of the power expansion system were also derived. Then, the circulating current of each parallel inverter was analyzed when the drives were asynchronous, and the zero-voltage-switch (ZVS) control strategy was given. Finally, a 1.2 kW IPT system power expansion device based on the separation compensation network was built for experimental verification. Experimental results showed that the ratio of the output power of each parallel inverter was about 1∶2 and all of them achieve ZVS operation, and the overall transmission efficiency from DC to DC of the power expansion system was 92.53% while the amplitude of the circulating current was 0.2 A, which proved the practicality and effectiveness of the proposed power expansion topology.
