Today's mainstream charging methods are directly transmitting power to our equipment through wired means, so the most intuitive way, the energy loss is also the most stable. However, because the length of the wire greatly limits the convenience of our charging. Therefore, to improve such a disadvantage, wireless power transmission is born.
In this paper, we mainly study capacitive power wireless transmission. In view of the fact that wireless power transmission in the past is transmitted by inductive coupling, the way of inductive coupling is very large for the position, distance and wire of the coil. The impact of the study of capacitive wireless power transmission can improve the shortcomings of inductive wireless power transmission.
The paper is divided into three major blocks. The first block is analog and impedance-matched, and the high-frequency system simulation software (HFSS) is used to simulate the S-parameter in the 50MHz~1 segment of 1MHz, and then the impedance is matched to make the power transfer from one end to the other. Achieve the best efficiency. The second block is to make an experimental model and compare the difference between capacitive and inductive. In the third block, the corresponding circuits at the front and rear ends, such as the signal end and the rectifying end, are fabricated.
