单片机供电系统存在的干扰因素及抗干扰设计

The Disturbance Factor in the Microcontroller Power System and the Auti-disturbance Technique

为确保单片机系统正常工作,必须对其进行抗干扰设计.影响单片机系统可靠性的干扰因素主要来自电源,即供电系统.讨论供电系统存在的干扰因素,并提出改进措施和抗干扰设计的方案,具有现实意义.

We must design the microcontroller system with auti-disturbance technique,in order to keep its normal state in work. Power system is the main disturbance factor in the microcontroller from the source of electricity. This article ana-lyes the disturbance factor of the power system and raise a better measure and an auti-disturbance plan.
