Problems solved by technology

[0002] At present, the existing technology of diesel locomotives is: the diesel engine drives the auxiliary generator, and supplies power to the auxiliary system by controlling the excitation of the auxiliary generator; when braking with resistance, the braking energy is consumed through the braking resistor
The disadvantages of the above technologies are: a. The control is complicated and the power supply quality is not high; b. The space occupied by the locomotive affects the overall layout of the locomotive; c. The braking energy is all consumed in the braking resistor, which is not energy-saving and environmentally friendly.
