摘要
高清晰度电视的发展对偏转系统的偏转灵敏度提出了更高的要求,应用带有磁极的偏转系统可以提高偏转灵敏度,多段式的磁极结构可以实现自会聚。对三段式的二十极多磁极偏转系统的计算机辅助设计方法进行了介绍,得到会聚良好、具有较高偏转灵敏度的多磁极偏转系统。
With the development of HDTV, higher and higher deflection sensitivities of deflection systems are required. Incorporation of multi-magnetic-pole to the deflection system can considerably improve deflection sensitivity, because multi-magnetic -pole structure results in self-convergence. In this paper, computer aided design of the multi-magnetic-pole deflection system, including three stages with 20 pole pieces, was developed. Our results showed that the deflection sensitivity and the convergence of the deflection system markedly improve.
