|
摘要
为了避免弹载电子设备在导弹电源发生瞬态电压、浪涌、过压时受到损坏,结合对电源输入反接、过流、负载短路进行保护,采用LTC4364-2和IPB107N20N3G为核心芯片,设计了满足GJB181关于电源尖峰、浪涌要求,并具有电源输入反接保护,过压、过流保护功能的电源保护电路。该电路设计简单,电路参数可通过外围电阻、电容方便进行设置,并且体积小巧。试验结果表明,该电路的各项性能指标完全达到设计要求。该电路已成功应用于弹载电子设备中,取得良好的效果。
To avoid the harm to the missile-borne equipment caused by the voltage transients,voltage surge and overvoltage from the power system of missile. Simultaneously,to prevent reversed input of the power supply,over current and short circuit of load,the design adopts LTC4364-2 and IPB107 N20 N3 G as its primary chips to meet the requirements of the voltage surge and overvoltage in GJB181,and it has the function to prevent the circuit when reversed input of the power supply and overvoltage or overcurrent happened,which is characterized by simplicity,convenient parameter setting through the external resistors and capacities,and the circuit size is compact. Experimental results show that the performance of the circuit can meet the requirements. The circuit has been applied to missile-borne equipment successfully and performed well.
