高精度双向DC电源电流采样电路设计
<p>为适应双向DC/DC功率变换的电流采样需求,一种高精度高边电流采样电路被提出。其基本思想是在功率电路的高边串入采样电阻,借助电流镜原理并引入偏置电流电路,将双向电流均转换为正向电压输出。通过理论分析与仿真结合的方法对电流镜采样原理及4种不同的偏置电流电路方案进行对比,最后通过实验数据验证了高精度高边电流采样电路的有效性。实验数据表明,该采样电路可在-25~75℃的温度工作范围内,针对-10~
电动汽车永磁无刷直流电机控制器设计
<p>对某四轮独立驱动电动汽车轮毂电机进行研究,设计一种永磁无刷直流电机控制器.以STM32F103RBT6芯片为基础,对电机驱动电路、采样电路和保护电路分别进行硬件设计与分析;同时,采用模块化软件设计方案,对该控制器的软件系统进行升级.实验验证表明:所设计的电机控制器能使电机响应迅速、转速稳定、无超调,且电动车动力输出性能良好.</p><p>A permanent magnet brushles
PCROP区域函数无法被调用的问题与解决
<p>PCROP 为Proprietary code readout protection 的缩写，也就是说这是一个专有代码读出保护的功能。与RDP 对整片Flash读保护不同的是，它只是针对Flash 的某些特定区域进行代码的读写保护。所以它可以被用来保护一些IP 代码，方便进行二次开发。它存在于许多STM32 的型号中，如STM32F401、STM32F411、STM32F427/437、ST
STM32F4xx PCROP应用
<p>Proprietary Code Read Out Protection (PCROP) ----- 专有代码读取保护 现在产品开发过程中，二次开发将会越来越多，设计公司开发出自己产品后交给终端客户进行二次功能或补充开发，简称二次开发，设计公司某些程序代码不希望公开给终端客户，但同时又希望部分函 数功能可以给终端客户使用，这时就需要有一种专有代码保护机制供客户使用，STM32F4xx 芯片中
