| Abstract: | A doubly-forward-converter with multiplexed output based on UC3844 is introduced.The operating principle of this converter is analyzed in detail,and the methods of starting and control strategy are given in this article.This circuit owns adwmtages such as sim- ple,low cost,high operating frequency and adaptability.Meanwhile,in this paper proposed two kinds of output scheme to come with different precision requirement for the outputs.The converter has higher quality than normal doubly-forward-converter.The Experi- ment results verify the feasibility and virtue of this circuit. |
