开关电源产品广泛应用于工业自动化控制、军工设备、科研设备、通讯设备、电力设备、数码产品等领域。传统的开关电源多为单入单出,多个供电端口就需要多个开关电源,用于大型设备与较为复杂的实验上存在诸多麻烦,不仅大大提高成本更降低了设备的集成度。为了解决上述问题,本文介绍了一种基于UC3842的双入多出开关电源,直流、交流双模输入,7路直流输出。
Switching power supply products are widely used in industrial automation and control, military equipment, research equipment, communications equipment, electrical equipment, digital products and other fields. The traditional switching power supply is mostly single-in and single-out, and multiple power supply ports require multiple switching power supplies. There are many troubles for large-scale equipment and more complicated experiments, which not only greatly increase the cost but also reduce the equipment integration. In order to solve the above problems, this paper introduces a dual input and multiple output switching power supply based on UC3842, DC, AC dual mode input, 7 DC output.
