Study on Mine-Used Battery Locomotive Charging System
According to the insufficiency of large volume, high cost and poor dynamic response in the traditional mine-used battery locomotive charging system. This paper presents a design scheme on this system based on DSP TMS320F2801 which directly using SPWM conversion control technology, generating the SPWM wave through DSP control chip and convert the alternating current under the mine into the corresponding pulse charging current. The results show that the system can achieve the goal that well system stability, good dynamic performance, control circuit simplified, high charge efficiency and low cost.
