资料介绍

为了减小瞬态电压、浪涌电压、输入电源极性反接、负载短路对机载电子设备造成的危害,针对当前航空直流+28 V电源系统的特点,提出了一种解决直流电源输入过压浪涌、输入欠压浪涌、输入电源极性反接、负载短路或过流导致设备损坏的方案。该方案以LTC4364和APL502 L为核心芯片。首先介绍了该电路的主要特点,接着分析了电路的工作原理和参数设计,最后对该电路进行了仿真分析和实验电路测试。实验结果表明,该电路各项性能指标良好,完全达到设计要求。该电路已成功应用于某电台中,且工作良好。

In order to reduce the harm to the airborne electronic equipment caused by the transient voltage, surge voltage,reverse input of the power supply and the short of the load,according to the characteristics of the current +28 V DC airborne power system,a solution is proposed which can overcome the harm caused by the input overvoltage,input under-voltage,reverse input and the short or over-current of the load. In the solution LTC4364 and APL502L are chosen as the core chips. The main features of the design are intro-duced,the operating principle is analyzed and the design of scheme is described,and finally the circuit op-timization and actual verification for the whole system are conducted. The results i...
