METHOD OF MANUFACTURING THE TRANSFORMER COIL

METHOD OF MANUFACTURING A TRANSFORMER COIL, WHEREIN LEFT AND RIGHT SIDE SURFACES (2 AND 3) OF A COIL WIRE (1) ARE VERTICAL AND PARALLEL, UPPER AND LOWER SURFACES (4 AND 5) OF THE WIRE (1) HAVE AN UPWARD CONVEX SURFACE AND A DOWNWARD CONVEX SURFACE, RESPECTIVELY. THEREFORE, WHEN THE COIL WIRE (1) IS WOUND FROM RIGHT TO LEFT, THE RIGHT SIDE SURFACE (3) OF A NEW WINDING COMES INTO CONTACT WITH THE LEFT SIDE SURFACE (2) OF A PREVIOUS WINDING, AND WHEN THE COIL WIRE (1) IS WOUND FROM LEFT TO RIGHT, THE LEFT SIDE SURFACE (2) OF A NEW WINDING COMES INTO CONTACT WITH THE RIGHT SIDE SURFACE (3) OF A PREVIOUS WINDING. FURTHER, THE LOWER SURFACE (5) OF A WINDING OF AN UPPER WINDING LAYER IS PLACED IN A SPACE BETWEEN THE UPPER SURFACES (4) OF TWO WINDINGS OF A LOWER WINDING LAYER, THEREBY REDUCING SPACES REMAINING BETWEEN WINDINGS AND REALIZING MAXIMUM TRANSFORMER EFFICIENCY USING A SMALL NUMBER OF WINDINGS.
