Abstract
Designing a good flyback power supply is useful but not so easy for hardware designers.This paper aims at discussing the principle of flyback and introducing a new design process of flyback switching converter which can be used for various PWM IC controlling.This paper advances the formula for calculating the primary inductance in transformer based on the maximum duty cycle and researches the characteristics of flyback voltage with a purpose of discussing the formula of flyback voltage.
