The present invention provides a multilayer transformer PCB structure for an electric car, which includes a base substrate formed of a predetermined material to form an basic layer of a transformer PCB, first and second connecting copper tabs horizontally formed in plural on both surfaces of the base substrate by patterning process a copper (Cu) material so that the copper (Cu) material has a predetermined thickness, thereby forming inner layer circuits coupled to battery cells, and third and fourth connecting copper tabs stacked on a top surface of the first connecting copper tab and a top surface of the second connecting copper tab by patterning process a copper (Cu) material several times so that the copper (Cu) material has a predetermined thickness, thereby forming outer layer circuits coupled to the battery cells, and a method of manufacturing the multilayer transformer PCB for an electric car. According to the present invention configured thus, the transformer PCB for an electric car has a structure in which a conductive material having a predetermined thickness is stacked in a multilayer form, and thus an increased quantity of charges to be treated is highly distributed as the conductive material having a predetermined thickness is stacked on an inner layer and an outer layer in a multilayer form, thereby maximizing current efficiency. |
