Abstract With the development of technology, the renewal speed of mobile phone, PC and computer is getting faster and faster. The energy source also plays an important role in this process. The disadvantages of traditional charging mode have been more and more obvious and this mode has been discharged by us. What we need is a wireless charging technology which can be used by electronic devices. This paper designs a wireless charging system based on magnetic coupling resonance, including transformer, rectification, voltage stabilization, PWM, emission, receipt. The system can achieve electric energy transmission in several centimeters and gain a stable voltage, which has the advantages of better effect of energy transmission, low cost, easily realized, safe and broad applied targets.
