【摘要】 变频调速系统设计可以分为两个重要部分,软件设计与硬件设计。本设计首先简要阐述了变频调速的基础技术,SPWM理论及常用的设计方法等。然后对变频调速的硬件做了系统电路地描述。对整个系统的主电路、控制电路、各种保护电路及控制实现的软件都进行了系统的分析。主电路部分给出了整流、滤波、逆变器等器件各个环节的参数的计算。控制电路采用TMS320F2812、显示电路、输入电路、检测电路等,并配备了系统保护电路。在硬件电路的基础上,用MATLAB工具对系统进行了开环和闭环系统的SPWM仿真。仿真实验结果表明,这些设计使系统能够可靠工作,运行状态良好,达到了设计目的。最后给出了各个软件设计的系统流程图。更多还原

【Abstract】 The variable speed can be divided into two important parts: soft design and hardware design. The design firstly explains the basic techniques. of the variable speed, the theory and method of the SPWM. Then the major hardware circuit is introduced,Especilly TMS320F2812 and IPM. The calculation about parameter is made in the major circuit. At the same time the security of the circuit was equipped. DSP was regarded as the controller core of the SPWM. We establish a system model which control system speed open and close loop with SPWM,we simulate and analyze the control system through MATLAB.The simulation results demonstrate that it is a high value to popularize and apply the controlling system. Finally The design also gave the flow chart about the soft design.更多还原
