Wireless charging method for general mobile phone based on Qi-standard

摘要

According to the Micro-USB wired charging interface for smart phone used prevalent worldwide,an idea of wireless charging for mobile phone based on external coil is proposed.In the paper,a theory of wireless charging for mobile phone under qi-standard is introduced.In addition,the main circuit topology of wireless charging device and the method to eliminate ring are illustrated.Then the wireless charging device had been designed and made,the result from the experiment data shows the feasibility of the method.
