Abstract

This paper discuses the printed circuit board (PCB) winding of the contactless power transmission system comparing the traditional transformer power transmission system. In this study, the contactless power transmission system is successfully applied to the wireless mouse for stable power supply. To examine the feasibility of the proposed system in this paper, a contactless power transmission system is developed with 10 W of contactless coupling transformer in primary input power and 0.2 W of secondary output power, which are about 2% efficiency. However, the design of contactless power supply for wireless mouse can be used under the mouse pad to decrease battery consumption and reach the purpose of energy saving, carbon reduction, and environmental protection.
