Research on High Efficiency Charging Technology of Electric Locomotive

针对矿用电机车充电装置充电效率低的问题,提出了一种基于改进型Buck电路的矿用电机车充电装置,其可以实现电感电流连续导通,进而实现输出电压与输入电压成正比,以及IGBT软开关。最后,进行了仿真与实验验证本文结论的正确性。

For motor vehicle charging device for charging the problem of low efficiency, this paper proposes an improved charging device for mine electric locomotive based on Buck circuit, which can realize the inductor current continuous conduction, so as to realize the output voltage is proportional to the input voltage, and IGBT soft switch. Finally, simulations and experiments are carried out to verify the correctness of the conclusions.
