Description

Technical Field

[0001] The utility model relates to the technical field of direct current conversion modules, in particular to a constant power direct current conversion module. Background Art

[0002] A constant power DC conversion module is used in the elevator system. It is a device that can convert and store the regenerative electric energy generated by the elevator during operation. When the elevator goes down with a heavy load or goes up with a light load, it will generate mechanical energy. This energy can be converted into electric energy through the elevator's traction system. The constant power DC conversion module can convert and store this regenerative electric energy for use by other parts of the elevator system. The constant power DC conversion module for elevators can not only improve the energy utilization efficiency of the elevator system, but also ensure the stability and safe operation of the system. At present, common DC conversion modules lack effective protection and are easily affected by physical damage and environmental factors, which leads to a reduction in their service life.
