Claim 14:
15. The method according to claim 12, wherein the preparation of PCB comprises:
forming a first transformer primary coil on a first PCB layer and a second transformer primary coil on a sixth PCB layer;
electrically connecting the first transformer primary coil with the second transformer primary coil to form the transformer primary winding;
forming a first transformer secondary coil on a second PCB layer and a second transformer secondary coil on a fifth PCB layer;
electrically connecting the first transformer secondary coil with the second transformer secondary coil to form the transformer secondary winding;
disposing the first PCB layer adjacent to second PCB layer such that the first transformer primary coil is magnetically coupled with the first transformer secondary coil to form a first transformer layer assembly;
disposing the fifth PCB layer adjacent to sixth PCB layer such that the second transformer primary coil is magnetically coupled with the second transformer secondary coil to form a second transformer layer assembly;
forming a coupler primary coil on a third PCB layer to construct the coupler primary winding;
forming a coupler secondary coil on a fourth PCB layer to construct the coupler secondary winding; and
disposing the third PCB layer adjacent to the fourth PCB layer such that the coupler primary coil is magnetically coupled with the coupler secondary coil to form a coupler layer assembly.
