摘要
介绍了开关电源设计中需要考虑的几个基本问题 ,包括频率的确定、最大占孔比Dm的确定、逆变变压器的设计和开关功率管的选择 ,并以一种 1kW的PWM大功率半桥式开关电源为例 ,详细介绍实际的开关电源设计方案 。
In this paper, some basic problems about switching power supply have being considered. With the example of a half bridge PWM high power switching power supply, the design of switching power supply is introduced in detail. Then the experimental result is given.
