摘要
SG3525是一款单片集成PWM控制芯片。文中以SG3525为控制核心,运用高频逆变、软开关和电容补偿等技术,设计了一种具有过流保护功能的非接触式小功率电能传输系统样机。经实验表明,该系统原、副边距离为1 mm时,电能传输效率可达到78.9%,实现了能量的高效传输。
SG3525 is a type of monolithic integrated PWM control chip. The system is designed with SG3525 as control core, and a stand-alone prototype of contactless low-power power transfer system possessing the over-current protection function is completed by applying various techniques including high frequency inverter technology, soft switching technology and capacitance compensates technology. The experimental results show that the power transfer efficiency can reach to 78.9% when the distance is lmm between primary side and secondary side, which proves the system can realize the high-efficiency transfer of the power.
