高效无线供电模块设计研究

摘要

提出一种高效的无线供电模块设计方案，该设计结合了现有的 DSP 技术、电磁感应技术和开关电源技术，提高了开关电源的转换效率，并省去了电源线。由于传输距离受限，其应用价值还比较有限，然而整个模块的电路设计使其工作稳定、结构简单、信号接收端微小化，基本符合实际应用的可接受度。%The design proposal of the efficient wireless power supply module which combined the DSP technology, electromagnetic induction technology and switching power supply technology enhance the transfer efficiency of switching power supply and can work without power lines. The application value is relatively limited for the limitation of transmission distance, while the circuit design of the whole module has certain advantages like work stabilization, simple construction and signal receiving terminal miniaturization which can basically conform to practical acceptability.
