1MHz换能器驱动电路的设计
<p>超声波换能器作为一种实用的检测手段，能实现声波所携带的信息和电能之间转换。它的性能优良，价格低廉，操作方便，易于调试，因此在工农业生产中发挥着重要的作用。但目前换能器驱动电路的发射频率多为40 kHz，本文针对1 MHz的超声波换能器电路进行了设计，主要介绍了它的发射驱动电路和接收驱动电路的设计方案，并对它们的功能进行了详细地说明。最后搭建实验平台，并对电路的输入、输出模块进行了测试。实验结
基于UCC28019的PFC电路设计
<p>为设计高效率、低损耗的PFC电路,本文基于UCC28019进行电路设计。以UCC28019输出的PWM波形来控制Boost升压斩波为核心电路,使电路中的电容交替地充放电、电感交替的储存和释放能量,最后实现在输入AC20V~24V电压情况下稳定输出DC38V。测试结果表明,系统实现效率为95%左右,电压调整率小于1%,电源功率因数0.99。交流输入电压为19.0-25.8 V时,输出直流电压稳
