摘要
文中针对电气电子类学生实验教学需要,基于L298N的H桥功率变换器设计了一套可由单片机或DSP等微控制器驱动的微直流电机数字控制平台,并详细说明了微直流电机功率驱动电路的基本原理和制作。本实验教学用微直流电机数字控制平台制作简单,方便实用,易于维护,可满足电气电子类学生的教学需求,使学生掌握直流电机基本原理、PWM控制原理,ADC变换等知识点。
Based on the L298N H-bridge power converter, the micro DC motor＇s digital-control platform which can be controlled by MCU, such as SCM or DSP, is designed in this paper for experiment teaching of the college students majoring in electrical and electronic engineering. The basic principle and manufacture of micro DC motor driving circuit are described in details. The experimental platform made simply is convenient and practical, and is easy to maintain. It can meet the teaching requirements for the college students majoring in electrical and electronic engineering, help the students to master the principle of micro DC motor, PWM and ADC conversion.
