斩波器设计与应用

摘要

本文以绝缘栅型晶体管IGBT作为开关元件,利用TL494进行脉宽调制,改变IGBT的开关时间,得到可调的直流电压电路做了比较深入的实验研究,并做了一定的调试。%Based on the DC chopper on principle,on the basis of the actual application of the typical chopper circuits are compared and analyzed to determine the design of this graduate of the design.Focus on the use of insulated gate IGBT as a switching transistor components,through a PWM TL494,change IGBT switching time,have adjustable voltage DC Circuit done a more in-depth theoretical and experimental research,and to do a certain amount of debugging.
