为解决移相全桥电路驱动及相角控制问题,设计了一种数字控制的移相全桥驱动电路.以TPL521为光耦隔离、IR2110为栅极驱动芯片.由DSP产生PWM信号,经过光耦隔离和逻辑电路后送至IR2110进行相角控制.文章对IR2110驱动电路原理进行分析及参数进行设计,对TMS320F28335进行设置并给出部分代码.实验结果表明：通过TMS320F28335可产生 ...

sscom是一款主要是用于蓝牙的调试的专业串口调试软件。用户可以通过该多串口调试工具来调试蓝牙，检测串口的状况。该软件可以及时显示存在的串口号，如果用户增加了usb转串口设备，串口号就会出现在列表内。能够支持110-256000bps波特率，设置数据位（5678），校验（odd，even，mark，space）、停止位（1，1.5，2），并发送 ...

Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In ...

一.基础理论锁相环路（Phase Locked Loop）是一个闭环的相位控制系统，它的输出信号的相位能自动跟踪输入信号相位。系统框图如下：当0，（1）与0：（1）相等时，两矢量以相同的角速度旋转，相对位置，即夹角维持不变，通常数值又较小，这就是环路的锁定状态。从输入信号加到锁相环路的输入端开始，一直到环路达到锁定的全过 ...
