摘要
以电力机车110V电源为研究背景,利用TI公司的数字信号处理芯片TMS320F2812作为主控制器件,采用电压外环、电流内环的双闭环控制策略,通过CAN总线进行信息传输,用软件编程的方式实现各个并联模块的智能均流。试验证明,电源带载运行稳定,均流效果好。
This paper researched the 110V power supply for electric locomotive,which used TI＇s TMS320F2812 digital signal processing chip as the CPU and adopts the double closed-loop controlling（voltage loop outside,current loop inside）.The message were transferred through the CAN bus and intelligent current-sharing of the parallel modules had been realized by using the software.The experiments show that the power with load run stably and current-sharing effects is well.
