Embodiment Construction
[0038]In the following, the high-voltage transformer in accordance with an embodiment of the present invention will be explained in detail with reference to the accompanying drawings.
[0039]FIG. 1 is a plan view showing the exterior of the high-voltage transformer in accordance with an embodiment of the present invention, whereas FIG. 2 is a wiring diagram showing a characteristic concept of the high-voltage transformer.
[0040]The high-voltage transformer 11 in accordance with this embodiment shown in FIG. 1 is an inverter transformer used in a DC / AC inverter circuit for simultaneously discharging / lighting two CCFLs (cold cathode fluorescent lamps). Its primary coil 45 and secondary coil 47 are wound about a common rod-shaped magnetic core (hidden in FIG. 1) made of ferrite or the like which is a soft magnetic material, and are electromagnetically connected to each other by the common rod-shaped magnetic core.
[0041]An insulating partition 44 is disposed between the primary coil 45 and...
