DSP (digital signal processing) control board compatible with TMS320F28x series

Abstract

The invention belongs to the technical field of current transformer control, and relates to a DSP (digital signal processing) control board compatible with a TMS320F28x series. The DSP control board comprises a DSP2812 minimum system board, a DSP28335 minimum system board and a bottom board. The DSP2812 minimum system board and the DSP28335 minimum system board can be connected with the bottom board separately. The DSP2812 minimum system board comprises a TMS320F2812 control chip, a reset circuit, a JTAG (joint test action group) download port, an external expansion RAM (random access memory), an external expansion Flash and external expansion pin interfaces, the reset circuit, the JTAG download port, the external expansion RAM, the external expansion Flash and the external expansion pin interfaces are all connected with the TMS320F2812 control chip, the reset circuit provides reset signals for the control chip, the external expansion RAM and the external expansion Flash are used for expanding program codes and compiled code memory space of the DSP control chip respectively, and an IS6ILV51216 chip is adopted to the external expansion RAM while an SST39VF800 chip is adopted to the external expansion Flash. The DSP control board has the advantages that compatibility is realized, requirement on DSP self function maximization is met, and complex algorithm control in the field of new energy such as wind power is achieved.

Description

technical field [0001] The invention belongs to the technical field of converter control, and in particular provides a DSP control board compatible with TMS320F28x series, which is suitable for converter control systems in new energy grid-connected fields such as motor control and wind power generation. The DSP functions of the TMS320F28x series are comprehensive and have good flexibility, compatibility, selectivity and applicability. Background technique [0002] At present, DSP has the characteristics of high-speed processing complex computing capabilities, versatility and flexibility. DSP is widely used in the fields of digital control and motion control, such as motor control, wind power and other new energy converter control fields. The traditional DSP control board generally uses a single DSP (Digital Signal Processing, digital signal processing) chip as the control core, and the DSP control chip is welded and fixed with the control board. In normal experimental use, ...
