一种大功率直流开关电源的主电路设计

The main circuit design for a high power DC switch power supply

开关电源设计最重要的2部分是主电路和控制电路。根据大功率直流开关电源的设计要求,结合大功率直流开关电源的工作原理、电路的拓扑结构、运行模式的特点及相关技术参数,本文进行性能分析并计算各项参数,通过计算所得的数据结果选择各元器件,设计出各个独立模块,最后组装成大功率直流开关电源的主电路。

The most important parts for the design of switching power supply are the main circuit and the control circuit. According to the design requirements of the switching power supply of large power DC, combined with the working principle, the circuit topology structure, the characteristics of the operation mode and related technical parameters of switching power supply of DC power, the performance analysis and calculation of the parameters were executed and the components were selected based on the calculated data. Each independent module was designed. The main circuit of large power DC switch power supply was assembled successfully.
