摘要
开关直流稳压电源是实现电能转换和功率传递的主要设备。相较传统线性稳压电源,技术含量高,耗能低,应用方便。介绍了开关直流稳压电源的基本原理、主要技术要求及设计步骤。并以具体实例对较大功率的这种电源的主要功能电路的设计及元件参数的计算进行了详细介绍。
DC switch stabilized voltage supply is a main equipment achieving power conversion and power transmission. Compared with the traditional linear vohage stabilizer, is has high technical content, low energy consumption, convenient for use. This paper introduces DC switch stabilized voltage supply of the basic principle, main technical requirements and design steps. With the concrete instances to higher power switch dc power supply voltage, the main function of the design and the main components of circuit parameters are described in detail.
