Abstract

A high-insulation multilayer planar transformer () includes a pair of iron cores () and a circuit board integration (). The circuit board integration () is stacked between the iron cores () and has a through hole (). The circuit board integration () includes a first to a third insulating layers () and a first to a second coil windings (). The first and third insulating layers () include at least two insulating plates () stacked with each other respectively. The second insulating layer () includes at least one insulating plate (). The coil winding () is disposed between the adjacent insulating layers and surrounds the through hole () planarly. Therefore, the reinforced insulation requirement of safety regulations may be achieved.
