高性能开关稳压电源的研究

High efficient switch steady voltage source

设计一种目前较先进的零电流切换技术的开关稳压电源 .控制电路采用了脉冲调频技术 ,并在输出输入间使用了光电隔离管 ,因而整机较普通开关电源 ,不仅具有较好的纹波特性 ,而同时具有高效率、体积小等线性电源无法比拟的优越特性 .

This paper is an advanced design for switch steady voltage source with zero current cut exchange technology at present.The control circuit adopts pulse frequency modulation technology and uses photo electricity isolating transistor between export and input.As a result.this device is not only better ripple feature but high efficiency and small volume as well. These superior feature is better than linear power source.
