| Abstract: | 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. |
