摘要
分析了单端反激准谐振式开关电源的工作原理及实现方法,采用ONSEMI公司的NCP1337芯片制成了准谐振(QR)开关电源,详细分析了该电源的设计过程。给出了所研制电源的电路及其工作波形。通过实验验证了设计的合理性,证明了该电源开关损耗低、性能优越。
The principle and realization of Single flyback Quasi-Resonant switching power supply are described in this paper.A Quasi-Resonant Switching Power Supply with the control chip of NCP1337 manufactured by ONSEMI is made.The design- ing process of the power is analysised detailedly.The circuit and its operating waves of this power supply are given. As a result, one experiment verified the circuit.The experiment shows the rationality of the designing and the low swiitching loss.
