摘　　要：针对某型装备的数字化改造,介绍了一种基于单片DSP的双路伺服驱动电源设计。本设计以单片TMS320LF2407A为控制核心、以IPM模块作为开关器件,产生两路独立输出的伺服电机驱动电源。功率电路采用工作在单极倍频可逆PWM模式下的H桥结构。试验表明,该双路伺服电源工作可靠、动态响应快、噪音低。This paper introduces a design of double servo drive-powers based on single DSP in certain accouterment digital conversions. The DSP, 320LF2407A, produces two channel signals, used to control two servo drive-powers each other. Power circuit,H bridge structure, runs under the limited unipolar of double frequence reversible PWM model. Application indicates that the system is reliable, and has a quick response time, low noise.
