Transformer with novel structure

The utility model discloses a transformer with a novel structure, which relates to the technical field of transformers and adopts the following scheme that the transformer comprises a PCB (printed circuit board), a through hole is formed in the PCB, a flat coil is mounted above the PCB, and a magnetic core is mounted outside the flat coil; due to the fact that the flat coils are arranged to be connected in parallel and are in flat shapes, the device can bear large currents in the using process, then the multiple flat coils are connected in parallel on PCBLAYOUT to bear multiple times of large currents, meanwhile, the shapes of the flat coils are simple and the same, automatic production can be achieved, and production efficiency is improved. Winding of a conventional transformer structure is manually wound, automatic production cannot be achieved, efficiency is low, even if windings are wound by the same person, produced transformers are complex in parasitic parameter and poor in leakage inductance, DCR and s
