Multilayer transformer PCB structure for electric vehicle and method of manufacturing multilayer transformer PCB therefor

摘要

The present invention provides a multilayer transformer PCB structure for an electric car and manufacturing method for the same, which includes first and second connecting copper tabs horizontally formed in plural on both surfaces of a base substrate, 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 material several times as a predetermined thickness, thereby forming outer layer circuits coupled to the battery cells. 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, thereby maximizing current efficiency.
