HIGH-FREQUENCY DEFLECTION YOKE DRIVING SYSTEM AND THE METHOD OF HIGH-VOLTAGE GENERATION

For high Frequency video signals, display monitors for personal comput ers are required to shift from the horizontal scanning frequency f(H)= 15.75 kHz for conventional TV broadcasting to f(H)=64 to 80 kHz, which is called XGA. Shifting to high frequencies and restrictions on the w ithstand voltage of horizontal transistors decrease the inductance of deflection yokes, which is an obstacle in manufacturing deflection yok es. A study was undertaken on an operation to permit deflection/high v oltage integrated operation while keeping the inductance of the deflec tion yoke high. This paper reports the results.
