Magnetically Coupled Resonant Wireless Power Transmission Coil Temperature Rise and Parameter Optimization

Wireless power transmission has received extensive attention in the fields of aviation, aerospace, automobile, and new energy. With the increasing demand of power electronics, the power and transmission distance of wireless power transmission is increasing. The increase of transmission power leads to the increase of coil loss and the coil temperature rise. The temperature rise of the coil will cause problems such as material aging, insulation damage, and performance degradation, so the calculation and research of the temperature rise of the coupled coil are very important for the research of the wireless power transmission.
