Steady analysis and design of the flyback converter with different operation modes

In this paper ,steady principles of flyback converter with inductance continuous current mode,critical continuous mode and discontinuous mode are analyzed , the conclusion that flyback converter with DCM and CCM respectively has a similar output characteristic of current supply and voltage source is drawn.Performance of flyback converter with DCM and CCM is compared ,methods of selecting operation modes according to the load are pointed out.Design methods of the energy storage transformer are particularly presented. Prototypes of flyback converter are designed and experiments are made.Experimental results show agreement with the analysis.
