基于DSP的永磁电机数字交流伺服系统的硬件设计

Hardware Design of Digital AC Servo Systems Based on DSP

本文提出了一种基于DSP的数字交流伺服系统的硬件电路 ,包括主回路、驱动电路、存储器扩展、电流环和速度环的硬件电路设计。本系统采用价格便宜的电阻器来检测永磁同步电机的三相电流 ,功率主回路采用六单元的IGBT模块CPV363M4K来组成逆变桥实现直流到交流的逆变 ,控制器采用TI公司的TMS32 0F2 4 3。

The hardware circuit design of a DSP-based AC servo system is given, which includes a power board, a driver, an extended memory, a current loop and a speed loop.Cheap resistors are used to sense three-phase currents of the PMSM and an IGBT module CPV363M4K is used to compose the inverter. The TMS320F243 made by TI is chosen to implement the AC Servo System.
