The thesis is proposed to integrate a full-bridge LLC resonant converter and a loosely couple inductor for delivering the energy to DC load by wireless power transfer technique. According to LLC resonant technique, the switches in the primary side have zero voltage function. This helps to reduce switching losses and increase the efficiency of the converter. Here are the advantages of the proposed converter. (1)A loosely couple inductor can be utilized for wireless power transfer technique. ；(2)Resonant technique helps to achieve ZVS function for switches to improve the efficiency；(3)Leakage and magnetizing inductors can be integrated into the coupling inductor. This contributes to reduce the part numbers and design complexity. In the end of this study, a wireless power transfer converter for DC load is implemented. The efficiency will reach to 85%, and the highest efficiency is 89.5%. This work proves that the WPT converter can be achieved with high efficiency.
