Abstract

A charger power module provided by the present invention comprises a substrate assembly, a frame assembly, a supporting capacitor assembly and a blocking capacitor assembly, the supporting capacitor assembly is located at the bottom of the frame assembly, the frame assembly and the supporting capacitor assembly define a frame structure, the frame structure is fixed on one surface of the substrate assembly, and the frame structure and the substrate assembly define an accommodating cavity. The blocking capacitor assembly is located on the upper portion of the containing cavity and electrically connected with the frame assembly and the substrate assembly, the substrate assembly comprises a radiator substrate, a magnetic element and a power device electrically connected with the magnetic element, and the frame structure and the radiator substrate are connected to define the containing cavity. The magnetic element and the power device are integrated on the face, facing the containing cavity, of the radiator substrate. The charger power module provided by the invention is compact in structure, reasonable in layout and high in integration level, and can better realize miniaturization, light weight and simplified design of a charger.

Description

technical field [0001] The invention relates to the technical field of charger converters, in particular to a charger power module. Background technique [0002] Urban rail transit refers to the large and medium-capacity urban public transportation vehicles that run on different forms of rails in the city. The auxiliary power supply system used in urban rail transit vehicles generally includes an auxiliary inverter and a charger, wherein the charger provides DC power for the vehicle and charges the battery. Traditional chargers generally adopt the technical solution of three-phase half-controlled rectification, which requires low-frequency magnetic devices, resulting in a large volume and weight of the charger. With the rail transit industry's increasing requirements for on-board equipment reduction in size and weight, the demand for miniaturization and weight reduction of chargers has become increasingly urgent. [0003] At present, the method used to realize the miniatur...
