摘要

针对体现车载24V系统抛负载瞬态现象的测试波形，从能量吸收角度，根据测试波形的不同参数配置设计了电子设备电源输入端口过压保护电路中的关键器件，以确保电子设备的可靠运行。试验结果表明，该方法能有效指导过压保护电路的设计。%To reflect the test waveform of load-dump transient phenomena of automotive 24V system, we design the key components of the overvoltage protection circuit in an electronics power input port according to different parameter configuration of the test waveform and the principle of energy avsorption. The test results show that this method can effectively guide the design of the overvoltage protection circuit.
