ABSTRACT:
The invention provides an electric transformer for microwave ovens including a conventional magnetic circuit with three columns, and electric circuits insulated by carcases and covers made from an insulating material. The secondary carcase forms a particular housing for the secondary heating winding so that the secondary high voltage winding and the secondary heating winding are partially superimposed. Thus an excellent electric insulation is provided without loss of space.
