With the shift of horizontal driving frequencies to higher frequencies, the deflection yoke inductance becomes lower, causing various problems. To avoid these problems, the voltages on both sides of the deflection yoke were raised by impressing a negative pulse on a conventional flyback pulse (positive pulse) using LC resonance circuits and switching FETs. Thus, a deflection/high-voltage integrated circuit was developed, which can drive the deflection yoke having about three times higher inductance than the conventional one. This circuit configuration made it possible to reduce the high frequency loss, leading to an about 13% reduction in power consumption.
