| Wireless Power Transmission, also called Contactless Power Transmission, is a new kind ofpower transmission technology relative to the Traditional Power Transmission. the WirelessPower Transmission which is more economic and durable makes up for the insufficient of theTraditional Power Transmission, can safely and flexibly applyed in many kinds of specialcircumstances. As the Wireless Power Transmission technology increasingly matures, it is nolonger limited to the sole form that supplys the power to a single user, but turned to themulti-user form.At present, it lacks the research of the transmission mechanism about the Multi-userWireless Power Transmission system and how to improve the transmission efficiency of it indifferent cases which limits the further application of Multi-user Wireless Power Transmission.To solve these problems, the following jobs were executed in this thesis to achieve the maingoal of improving the efficiency: based on electromagnetic coupling principle, numerical modelof detachable transformer was established and detachable transformer was designed. Couplingmechanism of cone-shape coil,8figure coil and circular array coil was studyed and thesimulation model was established. What’s more, the magnetic field distribution and theinfluence on different system transmission efficiency and system stability when differentparameters change was studyed. |
