摘　　要：电源模块在通信系统电路单板中发挥着非常重要的作用,其性能的优良直接影响单板工作的稳定程度.提出利用防反接、防过流器件配合MOS管控制电源的缓慢启动,可以减小单板上电时冲击电流的强度,保护器件免受瞬间浪涌电流的影响,使单板能够正常地工作.详细地验证了设计的合理性和可行性,并且对电路设计的效果进行实际的对比测量.单板电源电压波形的稳定程度表明该方法能够满足通信系统电路单板对电源模块各项指标的要求.The power module plays an important role in the communication system circuit board,the stability of the circuit board based on the performance of the power module.Proposes to use the MOSFET to control the slow start of the power module with anti-reverse and anti-overflow,it＇s able to reduce the strength of the current of the circuit broad when the power is to be on,protecting the device from momentary inrush current,making the circuit board works properly.To verify the reasonability and the feasibility of the design in detail,and measure the effects of the design compared to others.The stability of power current waveform and the actual effect shows that the method can meet the requirements of the power module in the communication system.
