Abstract
The paper aims to develop a dual-slot type power-pickup suitable for the inductive power track system for contactless power transmission. A new strip type inductive power track with high magnetic flux density and magnetic field uniformity is proposed. By means of equivalent magnetic circuit model analysis, a dual-slot type power-pickup with high magnetic flux linkage is designed to improve the power transmission capacity and efficiency. To verify the contactless transmission characteristics of the proposed strip type inductive power track system, an inductive power track with 1.2 m long is constructed. The SPLSC topology is chosen as the compound resonant circuit of a full bridge inverter. In accordance with the experimental results, the maximum output power of overall system is 775 W with transfer efficiency of 64.58%, and the maximum transmission efficiency is 72.52% at an output power of 289.52 W.
