Title:
【発明の名称】陰極線管用の電子ビーム磁気偏向装置
Document Type and Number:
Japanese Patent JP2619638
Kind Code:
B2
Abstract:
An electron beam magnetic deflection system capable of raster and stroke deflection and providing minimum power dissipation in raster mode. Automatic switching (36; 20, 24, 28, 30) of the voltage demanded in raster mode is obtained by continuously sampling the yoke (L) current (I), the power supply voltage being switched in magnitude and polarity corresponding to the direction of change and polarity of the yoke current. By returning energy stored in the yoke (L) to the power supply during portions of the raster cycle, power efficiency is substantially enhanced.
