摘要
无线的通信系统(RRH)在功能结构上主要分为电源部分(PSU)、数字板(TRX)、射频部分(FEU)、功放部分(PA)等,其中电源部分是整个系统安全稳定工作的关键。通过对电源部分输入端的电压电流检测,一旦发现异常,系统立即响应给出相应的保护动作,从而保护电源本身以及整个通信系统的安全。对通信系统中电源的电压及电流检测设计方法进行探讨和归纳,并结合工程实践经验对各种设计方法的利弊进行了分析和总结。
Wireless telecom system in general includes Power Supply Unit （PSU）, Transceiver Board, Radio Frequency, and Power Amplification. Among them, the PSU is the key component to stabilize the whole system. Through monitoring the voltage and current of input part of the PSU, the control unit can respond immediately to protect the whole system when any abnormal phenomeon happens. This paper discusses the different detection methods of monitoring the voltage and current, and summarizes their advantages and disadvantages based on previous practical engineering design experience.
