基于DSP28335永磁同步电机调速系统硬件设计

摘要

主要基于DSP28335对永磁同步电机调速系统进行硬件设计。以TMS320F28335为核心，给出了系统主回路、PWM信号隔离驱动电路、电流检测电路、DSP电源电路、时钟及复位电路的设计方法，最后在硬件平台eEEP1000N电力电子实验装置进行实验调试。%This paper mainIy describes the hardware design of permanent magnet synchronous motor(PMSM) speed con-troI system based on the DSP28335.Based on TMS320F28335 as the controI center,and discusses the design method of main circuit,PWM signaI isoIation drive circuit,eIectric current examination circuit,DSP power circuit,cIock and reset circuit.
