Abstract
A new design method of flyback switching power supply is proposed for wide input voltage application. The new design method is called the boundary conduction mode (BCM) design.The finished flyback converter can operate in very wide input voltage from 80V to 500V reliably with the proposed method. The procedure of the transformer design is shown. And a 15W prototype with the new design method is developed. The experiments results show that the proposed converter can operate in the discontinuous conduction mode(DCM), BCM and the continuous conduction mode(CCM) with 12V output voltage and 15W output power. The experiments also show that the new flyback converter is suitable for very wide input voltage applications.
