摘要
分析了半波次级谐振的零电流准谐振变换器的工作原理 ,并研制了一台以UC3867为核心控制芯片的准谐振电源样机 ,对该电源进行了实验 ,结果表明准谐振电源具有开关频率高、效率高和纹波电压小等优点。
The operation principle of the half wave secondary side resonant ZCS quasi resonant converter is analyzed in this paper,and a prototype supply based on chip UC3867 is made.The experimental results indicate that quasi resonant supply has the advantages of high switching frequency,high efficiency and low ripple voltage.
