摘要
介绍了采用UC3843控制器的单端反激式开关电源的设计与实现,讲述了UC3843控制器内部电路及其特点,通过具体的多路输出开关电源设计实例分析了设计的主要步骤以及实际设计中应注意的问题,并提出了抑制噪声的措施,最后给出了该电源的性能测试数据。
In this paper, a thought of design and realization for a switch mode power supply of single terminal drive in reverse with UC3843 controller is introduced. The internal circuit and characteristics are analyzed. The problems and main process in practical design are analyzed through an example of switch mode power supply, and the methods of eliminating noise are presented. At last, the test data of this kind of power supply is presented.
