摘要
为了提高大学生对电子电路的设计、仿真、测试及调试的能力,结合电子技术课程内容,设计了基于PWM脉宽调制方式的DC-DC降压转换电路。通过对设计方案、Multisim仿真和实物连接与参数分析四部分的研究,帮助学生深入理解开关电源的基本原理,培养和提高学生分析问题和解决问题的能力。实物连接取得的效果基本达到Multisim仿真结果,实现了理论与实践的结合。
In order to improve students ability to design,simulate,test and debug the electronic circuitry,designing a DC-DC buck converter which based on the PWM pulse width modulation,with combined with the course of electronic technology.Through the study of the four parts of the design scheme,Multisim simulation,physical connection and parameter analysis,it helps students to understand the basic principle of switching power supply and cultivate and improve the students ability to analyze and solve problems.The effect of physical connection basically achieves Multisim simulation results,and realizes the combination of theory and practice.
