摘要
介绍了软启动电路的基本原理,对笔记本电脑上的软启动电路进行了详细的分析。通过具体的应用实例,比较了软启动电路与普通电路在电压启动时间和冲击电流上的差异。实验结果表明了软启动电路可以减缓启动电压的上升速率,降低瞬间冲击电流,保护电路元器件。
The article introduces the principle of soft-start circuit and analyzes its application on notebooks in detail.It compares the deference between the start-up voltage time and rush current for soft-start circuit and traditional circuit.The experiment result shows that soft-start circuit can decrease the rate of start-up voltage,reduce the surge current and protect components.
