Research of power supply dependability for brushless DC motor control based on DSP

基于TMS320F2812-DSP的方波驱动无刷直流电机控制具有良好的调速性能,而随着电子技术的飞速发展,微电子器件的供电电压逐渐降低。介绍了一种无刷直流电机控制中基于TMS320F2812-DSP的电源解决方案,给出了电源可靠性的详细设计,并利用Matlab对电源电压的效率进行了仿真研究,结果表明该设计在电源可靠性方面达到了更高的要求,取得了良好的效果。

The control system of DSP can make the brushless DC motor control（BLDCM） start fast and stable with wider area of speeding.With the high speed development of electronics technology,the voltage supplied from micro-electronic apparatus become lower and lower.A power supply solution for BLDCM based on TMS320F2812-DSP was introduced,and Matlab simulation was used to study the efficiency of the supply voltage.The results show that the solution meets demand better in dependability of the power supply.
