Panel transformer with multiple PCB (printed circuit board) panel superposed coils

The utility model relates to the technical field of transformers, and discloses a panel transformer with multiple PCB (printed circuit board) panel superposed coils, which comprises a first magnetic core and a second magnetic core which are wrapped in a high-temperature adhesive tape and are symmetrically arranged at the upper end and the lower end of the transformer, a first high-temperature diaphragm, a first PCB (Printed Circuit Board), a three-layer insulated wire, a second PCB and a second high-temperature diaphragm are sequentially arranged between the first magnetic core and the second magnetic core from top to bottom. The flat plate transformer adopts a sandwich mixed assembly structure of a plurality of PCBs and three layers of insulated wires, the effects of increasing the area of the PCBs and increasing the wire diameter can be achieved, and the limitation that a traditional single PCB flat plate transformer cannot realize a high-power and large-wire-diameter structure is solved through assembly ty
