Two-phase inverter를 활용한 스마트워치의 무선충전 시스템
- Abstract
- Recently, development of wearable device as worn on the body small portable computing devices is being active. Accordingly, many wearable devices have been sold in market. Among the many types of wearable device, Smart Watch can worn on the wrist and can watch phone call, Email, sns and letter. and currently many users love this device. Smart watches are usually charged with wire cable, so I develop the smart watch that can wireless charging. Wireless Power Transfer (WPT) systems have been intensively researched. Wireless power transfer system help us, can use electrical equipment easily. because disappear power cable. However, pickup device’s relative position of transmission system affect the power transfer efficiency. In this paper, suggest multi-feeder coil system to solve this problem using the 2-phase inverter have a phase difference of 90 degrees. In this case, generated magnetic flux is without being affected by the angle of rotation.
In this paper, suggest how you can effectively charge to smart watch using wireless charging.
