摘要
论述了一种基于UC3842 PWM控制器的降压斩波电源的设计。对该电源的主要构成部分做了分析,并给出了相应的实现电路。在此基础上研制了电源样机,并对其进行了试验研究分析。结果表明,采用该方法制造的降压斩波电源具有较高的效率、良好的动态和静态性能,满足了电力工程的要求。
A design of buck chopper power supply based on UC3842 PWM controller was discussed. Theanalysis for the main parts of the power supply was done, and the corresponding implementation circuits were given.A prototype which is based on the theory mentioned above was made, and experiments were taken to analyze theprototype. The results show that the power supply has higher efficiency, better dynamic and static performance, andmeets the requirements of the electrical engineering.
