嵌入式系统板级电源的研究

Study of PCB Power For Embedded System

提出嵌入式系统PCB板级电源的设计方法和要点。首先分析嵌入式系统板级负载的特点,讨论了不同负载的用电特点。然后讨论三种常用的板级电源的技术要点和适用场合,并进行特点比较。结合实例设计一个满足负载要求的板级电源。认为嵌入式系统的板级电源设计需要根据负载的要求确定主体方案和电源参数,结合电源的技术特点进行详细设计。对嵌入式系统的电源可靠性设计具有一定的参考价值。

Presents the key points and technique of PCB （Printed Circuit Board） power design for embedded system. Firstly, analyzes the features of PCB power for embedded system, and then discusses and compares the main technical points and applicability of three commonly used PCB powers. Gives a practical example of PCB power design to meet the load requirements. Suggestes that the design of PCB power for embedded system shouht determine the main project and power parameters according to the load requirements, and detailes the design combining with the technical features of the power. The study provides a reference to the reliability design of PCB power for embedded system.
