摘要
介绍了一种基于UC3844集成芯片实现双管正激多路输出的电路,分析了电路的工作原理,并介绍了电路启动和控制设计方法,该控制方法简单,成本低,工作频率高,实用性强,同时设计了两种输出方案来满足不同需要,与一般的双管正激相比有较高的实用价值,实验证明效果良好。
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.
