<p>PURPOSE:To provide a transformer device for generating high voltage which can take out a focus voltage from an electrical center point of a coil winding of an intermediate layer by placing two bobbins side by side, matching the center axes, and then by dividing a secondary coil winding into each of the above two bobbins. CONSTITUTION:A diode 36 is connected to the area between each layer of a secondary coil winding in series and in the same direction. In the coil winding process, the coil winding of a bobbin 15 and a bobbin 16 is formed separately. The ratio of the coil winding in the bobbin 15 to that in the bobbin 16 is determined by the position for setting electrical center point. Thus, the electrical center point is located at the connection part of the coil winding at the bobbin 15 side and that of bobbin 16 side so that central point voltage can be taken out from a terminal pin group 38 at the center and the voltage can be utilized as a focus voltage.</p> |
