Abstract

The invention discloses an AC-DC converter. The AC-DC converter comprises a converter main circuit and a control unit; the alternating current side of the converter main circuit is connected with an alternating current contact network and an alternating current load, and the direct current side of the converter main circuit is connected with a storage battery and a direct current load; the AC-DC converter is configured in such a manner that when the bow net of a railway vehicle is normal, the control unit controls the converter main circuit to lead electricity from an AC overhead line system to perform AC-DC conversion so as to supply power to the DC load and charge a storage battery; and when the bow net of the railway vehicle is abnormal, the control unit controls the converter main circuit to lead electricity from the storage battery to perform DC-AC conversion so as to supply power to the AC load and supply power to the DC load. The problems that in the prior art, a railway vehicleis stopped on a line for a long time to wait for rescue, and consequently intervals are blocked and the line is stopped are solved, the power is supplied to loads such as an air conditioner, the problem that at the moment, vehicle passenger experience is poor can be solved, and the operation experience is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of rail vehicles, and particularly relates to an AC-DC converter. Background technique [0002] During the operation of rail vehicles, due to natural disasters and other reasons, the pantograph network failure will cause abnormal interruption of the vehicle power supply. At this time, the prior art often uses batteries as the power source to maintain the DC load power supply of the rail vehicle, while AC loads (such as motors, air conditioners) Etc.) Forced to stop working, at this time the rail vehicle can only stop on the line and wait for rescue. In severe cases, it will cause blockage and line outage. When the ambient temperature is bad and the waiting time for rescue is too long, it will greatly affect the operation experience. Summary of the invention [0003] One of the technical problems to be solved by the present invention is to provide an AC-DC converter, which can release the energy of the battery co...
