Precise and power saved rectangular type deflection yoke

摘要

In order to reduce the deflection power of horizontal coil, development of rectangular type deflection yoke is proceeded. On the other hand, the characteristics spreads of this type deflection yoke grow worse. We quantitatively analyzed the real cause of these spreads by several experiments. As the results, improved coil and ferrite core system is confirmed to be effective to keep power saving and minimize the spreads at the same time.
