精选优质文档-倾情为你奉上开关直流降压电源（BUCK）设计摘要 本次电力电子装置设计与制作，利用BUCK型转换器来实现16V-8V的开关直流降压电源的设计。使用TL494作为控制芯片输出脉冲信号从而控制MOS管的开通与关断。为了将MOS管G极和S极隔离，本设计采用了推挽式放大电路。另外本设计还加入了反馈环节，利用芯片自身的基准电压与反馈信号进行比较来调节输出脉冲的占空比，进而调整主电路的输出电压维持在一个稳定的电压状态。关键字：BUCK型转换器，降压电源，TL494，推挽式放大电路。Abstract This Power electronic equipment design is used by BUCK to catch the goal of 16V-8VSwitch dc step-down power supply design.
