【Abstract】 The authors developed a novel flyback converter using Quasi-Resonant technology with NCP1205.In this paper analyzes the principles of the converter. The circuit and the method for determining the operation frequency of this converter are given.The experi-mental results show that this novel flyback converter has many characteristics. Such as good regulation ratio of the load; fast re-sponse; low output voltage ripple and low switching loss.更多还原
