| 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. This circuit owns advantages such as simple, low cost, high operating frequency and adaptability. Meanwhile, two kinds of output scheme to come with different precision requirement for the outputs are proposed. The converter has higher quality than normal doubly-forward-converter. The Experiment results verify the feasibility and virtue of this circuit. |
