Microchip公司的dsPIC33EDV64MC205马达控制板用来演示系统级封装(SIP)器件dsPIC33EDV64MC205的特性.该器件dsPIC® DSC是16位数字信号控制器,具有高速PWM,运算放大器,有三相MOSFET栅极驱动器的先进模拟集成电路.开发板的目标是驱动低压三相永磁同步马达或无刷DC马达(PMSM/BLDC). 输入DC电压10V-24VDC, +25C时RMS相电流为10A,马达相电流检测用来实现PMSM/BLDC马达的磁场定向控制,DC总线电流用来过流保护,DC总线电压检测,霍尔传感器/正交编码器接口能进行基于传感器马达控制算法,调试串行接口(USB to UART)基于Microchip产品MCP2200,开发板还具有用户接口如LED,电位计和按扭.板上加密认证IC ATECC508A允许进行基于IoT的马达控制应用演示.本文介绍了dsPIC33EDV64MC205马达控制开发板主要特性,框图,开发板测试点分布图和连接器分布图,电路图和PCB设计图.

 

The dsPIC33EDV64MC205 Motor Control Development Board is designed to demonstrate the features of the dsPIC33EDV64MC205 System in Package (SiP). This dsPIC® DSC is a 16-bit Digital Signal Controller featuring high-speed PWM, op amps, advanced analog integrated with a 3-phase MOSFET gate driver.  This board is targeted to drive a low-voltage three-phase Permanent Magnet Synchronous Motor or Brushless DC motor (PMSM/BLDC motor).  The board comes programmed to run dual-shunt FOC with PLL estimator using the Hurst BLDC motor as the out of the box demo.
