Abstract

The influence of transformer parasitics to low power high voltage output flyback converter is analyzed by using the transformer equivalent circuit, and through the way of simulation. Its mechanism under DCM working mode is discussed from the aspect of the flow of energy, stage by stage. Based on this analysis, the theory of balanced state of the low power high voltage output flyback converter is brought forward, which is a key of the design of the converter. Experimental results are presented to show that the analysis can explain the circuit performance well.
