Abstract

The invention provides a charger system and a railway vehicle. The charger system includes a charger, a storage battery and an auxiliary starting module, wherein the charger includes a first main circuit and a first control circuit which are connected with each other, and the first main circuit is controlled to work when a control voltage at the input end of the first control circuit is larger than a first preset voltage threshold; the auxiliary starting module includes a second main circuit and a second control circuit which are connected with each other, and the second main circuit is controlled to work when a control voltage at the input end of the second control circuit is smaller than a second preset voltage threshold; the input end of the second main circuit is coupled to a power grid, and the output end of the second main circuit is connected to the input end of the first control circuit, so that the power grid voltage can be converted into the control voltage of the first control circuit; the storage battery is connected to the input ends of the first control circuit and the second control circuit, so as to provide the control voltage to the first control circuit and the second control circuit. In case of serious power insufficiency of the storage battery, the auxiliary starting module is started to control the startup of the charger.

Description

technical field [0001] The invention relates to rail vehicle equipment, in particular to a charger system and a rail vehicle. Background technique [0002] As an important part of the auxiliary power supply of rail vehicles, the main function of the charger is to convert the grid voltage into a power supply voltage, thereby charging the vehicle battery and supplying power to other DC loads, such as traction systems and AC auxiliary power systems. The charger can directly affect the vehicle performance of the rail vehicle and plays an important role. [0003] However, the charger needs to control the power supply to work normally. In the prior art, a storage battery is usually used as the control power supply of the charger to provide a control voltage for the charger, thereby controlling the charger to work normally. While the charger converts the grid voltage into a power supply voltage to supply power to other DC loads, it also supplies power to the battery, entering a no...
