Analysis of flyback converter with constant current output

The basic principle of flyback converter with constant current output was introduced.The steady-state relationship of flyback converter with constant current output was derived according to flyback converter with constant voltage output.The concept of continuity degree was defined to facilitate the analysis of operation mode.The change process of continuity degree,duty cycle and peak primary inductor current were analyzed in detail with different input voltage and load resistance of flyback converter with constant current output.The change law was obtained.A flyback converter with constant current output was designed and the validity of the theoretical analysis was verified with the experimental and simulative results.
