Summary :

For high frequency video signals, display monitors for personal computers are required to shift from the horizontal scanning frequency fH=15.75 kHz for conventional TV broadcasting to fH=64 to 80 kHz, which is called XGA. Shifting to high frequencies and restrictions on the withstand voltage of horizontal transistors decrease the inductance of deflection yokes, which is an obstacle in manufacturing deflection yokes. A study was undertaken on an operation to permit deflection/high voltage integrated operation while keeping the inductance of the deflection yoke high. This paper reports the results.
