Low Ripple Design of the Switching Power Supply Used in Radar Receiver

介绍了某机载雷达接收机电源的实施方案。该方案采用开关电源代替线性电源,通过减少开关电源的输出纹波和干扰,满足接收机对电源的纹波要求。该方案提高了接收机电源的效率,减少了接收机电源的体积和重量,优化了接收机系统的设计。文中主要描述了接收机系统中所采用的开关电源的组成、各部分的作用、关键技术及解决途径。

A concept of designing a power supply for airborne radar receiver is introduced in this paper. This concept adopts switching power supply instead of linear power supply. The power supply ripple requirement of the radar receiver is met by reducing the output ripple and interference of the switching power supply. This concept increases the efficiency of the power supply of radar receiver, reduces the volume and weight and optimize the design of radar receive system. The paper mainly describes the constitution of power supply of the radar receiver system, role of every part, key techiques and means of realization.
