摘要
为了提高功率因数及消除谐波失真,设计了一款以L6562D为控制芯片的全桥式开关电源,该电源具有成本低、性能高的特点。简单介绍了开关电源的工作原理,L6562D芯片的内部结构及工作原理,并且给出了该开关电源的主电路图、控制电路图及实验波形。
In order to enhance power factor and eliminate harmonic distortion,a full-brige switching power supply based on contorlling chip of L6562D is designed,which has characteristics of low cost and high perfomance.The working principle of switching power,the internal structure and working principle of L6562D is presented in this article.And power supply circuit diagram,control circuit diagram and experimental results are attched.
