一种大功率数码管驱动方法

A Kind of High Power Digital Tube Drive Method

数码显示电路在生产生活中应用非常广泛,各种大小不同、功率各异的数码管及其配套的驱动电路品种繁多,设计与使用都很方便。但在某些紧急情况下,如果手头没有现成的驱动模块,还需要自己动手去设计相应的应急电路来解决问题。本文所述就是基于模数电路的针对SM 4118数码管的驱动电路,可取之处在于通过本文提供的思路和方案,适当变换参数之后,可以驱动大多数型号不一,功率不等的大功率数码管。且经过实物验证电路工作稳定,效果良好。

The digital display circuit in production and living is widely used.There is a large variety of all different sizes and power of digital tube and its driving circuit,it is very convenient for the design and use.But in some emergency situations,if there is no ready-made drive module in hand,it still needs yourself to design the corresponding emergency circuit to solve the problem.This paper describes the SM 4118 digital tube driver circuit based on module circuit.The desirable point in this paper is to provide the ideas and solutions,and after appropriately transforms the parameters;it can drive all of the large power digital tube with different models and unequal power.And the physical test shows that the circuit is working stable and the effect is good.
