| Popis: | This paper proposes a design method of the wireless power transfer system which obtains high power and high efficiency by using LC filter circuit in the transmitting side. This study forcuses on the maximum efficiency point of impedance. In the simulation, the proposed design achieved 2.5kW output power with the efficiency of 73%. In the experiment, the proposed circuit achieved 1.8kW wireless power transfer at the maximum efficiency point. The proposed circuit could achieve 3.1kW output WPT when input voltage was increased. |
