| Abstract: | Multiple output single-ended flyback switching power with high power factor is designed.The design of main circuit is focused on the calculations of high-frequency transformer including the calculation of inductance,core selection and the calculation of air gap.Power factor correction technique uses SA7527 integrated controller to eliminate current harmonics.Simulation results show that the output voltage keeps stable,input current harmonic content decreases,and the power factor is improved. |
