Abstract

The principle and realization of fly back quasi-resonant switching mode power supply are described in this paper. The general design consideration for some key circuits is presented

the cause of power consumption on MOSFET on-off is anatomized and the means of reducing it are put forward. Then a 24V1A high efficiency isolating quasi-resonant power supply with the SMPS chip IRIS4015 produced by IR Company is realized

and relevant circuit diagrams and operating waveforms are given.
