General-purpose control platform based on dual DSPs for power electronic converters

为了满足多种电力电子变换器对其控制平台的不同要求,缩短开发时间,实现控制平台硬件的通用化和软件的模块化,在基于双定点数字信号处理器(DSP)TMS320LF2407的大容量变换器专用控制平台的基础上,提出了电力电子变换通用控制平台的设计目标。描述了基于定点和浮点DSP(TMS320F2812和TMS320VC33)的通用控制平台各单元的设计方法。介绍了基于MATLAB实时工具箱(RTW)的调试方法。实验结果验证了设计和调试方法的正确性和可行性,该通用控制平台达到了设计目标。

Power electronic converters have various kinds of control platforms. Based on a special-purpose control platform with dual Digital Signal Processor-DSPs （TMS320LF2407） for a high power converter, this paper describes the design method of a general-purpose control platform. The control platform uses a fixed-point DSP （TMS320F2812） and a floating-point DSP （TMS320VC33）. Using matlab real-time workshop （RTW）, the general-purpose control platform was tested, and the modularized software was designed. Experimental results validate the correctness and feasibility of the methods and that the general purpose control platform satisfies the design targets.
