With a view to develop high accuracy servo system,this paper gives a detailed analysis on mathematical model and character of PWM driver,puts forward a simple rotational velocity estimator. On this basis the paper developes a new PWM driver suitable for medium-small power DC torque motor, This driver uses VMOS devices, has two driving methods,isolates power cicuit from signal circuit,and has characteristics such as wide frenquency width,high anti-disturbance ability,self-protection,rotational velocity estimation output,simple structure,etc. The driver has been applied to a practical servo system, which reached very high accuracy.

本文从研制高精度随动系统出发,详细分析了PWM驱动器的数学模型及特性,提出一种简单易行的转速估计器,并在此基础上开发出一种适于中小功率直流力矩电机的新型PWM驱动器。该驱动器采用VMOS器件,两种驱动方式相切换,强弱电隔离,具有频带宽、抗干扰能力强、自保护、转速估计输出、结构简单等特点,应用于实际随动系统中,能使系统达到很高的精度。

A 3-lead ECG amplifier for clinic monitors is introduced. It is furnished with auto-detection of lead fault and pace-maker detection function, and is controlled by a personal computer, which manipulate the lead selector, overdriving elimination circuit, the gain and the frequency range of filter. The circuit also adopted three kinds of isolation technique (namely, isolated ECG signal with A/D converter, isolated PC pulse signal with the patients, and isolated power supply) to secure the patients....
