A planar transformer, a power conversion circuit, and an adapter, is provided to improve noise suppression performance. The planar transformer includes a magnetic core and a printed circuit board (PCB) winding board, where the PCB winding board includes a primary winding, a secondary winding, a shielding winding, and a compensation winding. In embodiments of this disclosure, the shielding winding and the compensation winding that has a plurality of turns of coils are disposed between the primary winding and the secondary winding of the planar transformer. The shielding winding can shield electric field coupling between the primary winding and the secondary winding, thereby suppressing a noise current between the primary winding and the secondary winding. Common mode noise generated by the compensation winding cancels common mode noise flowing to the secondary winding or the primary winding, to minimize common mode noise of an entire system.
