By example analysis and experiment result compare,it introduces the usage and peculiarity of Multisim 2001 software platform of EDA technology in design type of experiment study on digital circuits,the advantages and disadvantages of EDA technology experimenthave been compared with actual operation,the important of combining"imitation experiment"and"material experiment"in design type of experiment of digit circuit teaching is put forward in this paper.

目前，国内高校的数字电路实验教学模式主要以2种方式进行：一种是完全采用常规的TTL逻辑器件(如逻辑门、触发器等中小规模集成电路)进行硬件连线测试，大多采用面包板或由多个双列直插座组成的各种实验箱。这种方式容易出现器件接触不良，接线不慎而烧坏芯片、电源等故障，学生实验课时得不到有效利用，影响对学生综合设计性实验能力的培养与提高。

The module integrates dual insulated driving and special protection circuits. It has high push-pull driving capability, bootstrap power supply technology and is easy for miniature design of inverter. The paper also introduces the application in portable diesel engine generator inverter and discusses some attention items in practical application.

该驱动模块内部集成两路独立驱动和独特的故障"局域网"保护电路，驱动能力强，体积对装小，易于逆变器的小型化设计，并介绍了该驱动模块在便携式柴油发电机逆变电源中的应用，讨论了设计中应注意的问题。

The new features include the distinguishable ground fault LED, true input to output mapping, a power supply expansion board, and a larger chassis on the PS-8. The units can be used in a split mode operation, allowing the independent operation of the two inputs to any of the outputs.

PS-6和PS-8具备了新的特征，包括可识别的接地故障LED、输入与输出图示、电源扩展板和PS-8大底盘等装置，各装置可在分割模式下运行，允许相互独立的两个输入和任何输出同时工作。

The objective of the thesis is to present newly developed AC driver and protection circuits for light emitting diode. The LED modules for each upper and low arm are with pulse-width modulation control in every half fundamental cycle. The indication and protection circuits act whenever short circuit and open circuit of LED module occur. Moreover, the current path is switched off when there is a short circuit of LED module.

目前一般白光发光二极体的驱动器，皆是使用直流电源驱动，本文利用发光二极体本身单向导通的特性，将发光二极体串接成桥式整流器的方式，只需控制流经中间路径的电流周期，就可达到调整发光二极体亮度之目的，并且增加发光二极体故障时的保护指示电路。

On the other hand, when mains fails, the base of transistor T2 becomes low and it conducts.

另一方面，当电源发生故障，T2的基晶体管变得很低，它的行为。

Shut OFF the power switch and pull over if there is any MALFUNCTION of the system.

关闭电源开关和拉过来，如果有任何系统的故障。

The quality of the neutral line and its grounding will influence directly to the operation of the combined hi-frequency switching mode power supply.

交流供电线路中的中线及中线接地质量的好坏，对通信用高频开关组合电源的工作有直接影响，实际应用中经常出现因中线及中线接地故障造成设备损坏，因此需加强对中线的维护。

In a long-term work in practice, we find that the power supply caused by disorders such as the phase sequence, it will lead to failure of electrical equipment.

在长期的工作实践中，我们发现电源相序如造成错乱，则会导致用电设备发生故障。
