Title Design of Power Electronic Measurement and Control Platform Based on TI - DSP Platform

Abstract：In order to meet the different requirements of various power electronic converters to its control platform, the development time is shortened, the generalization of the control platform hardware and the modularization of the software are realized.This paper focuses on the design of TMS320F28335 as the core module of power electronic converter monitoring and control platform. The platform is versatile and suitable for a wide variety of converters. In this paper, a one-way DC / DC converter for the measurement and control object detailed analysis of the system design of the module hardware circuit and software program design. The system control platform computing performance, with good versatility and scalability. In the experiment, I prepared the DSP control system program in CCS6.1 development environment, introduced the Main function, read the serial command function, read the serial data function and judge the design idea of the working mode function and give some code. The experimental results verify the correctness and feasibility of the design and debugging methods, and the common control platform achieves the design goal.
