Description

technical field [0001] The invention relates to the technical field of braking of electric locomotives, in particular to a motor all-electronic regenerative braking energy recovery system. Background technique [0002] At present, electric energy is widely used as clean energy to drive various electric locomotives, such as pure electric vehicles, hybrid vehicles, fuel cell vehicles, electric buses, rail trains, elevators, cranes, etc. [0003] Studies have shown that the braking energy of electric locomotives accounts for about 31%-57% of the driving energy of the vehicle's power system. The recovery and utilization of regenerative braking energy is of great significance for energy conservation. The braking energy of electric locomotives has not been fully developed and utilized so far. The regeneration of braking energy is conducive to the efficient recovery and utilization of energy, which can reduce carbon dioxide emissions, have no noise pollution, meet the requirements ...
