Abstract

In a directed beam cathode ray tube (CRT) display, the X and Y deflection output stages are the most significant users of power and so dictate the design of the power supplies and cooling systems. As the need for higher EHT voltages becomes apparent for higher resolution displays or color together with wider deflection angles, the power requirements of the deflection amplifiers will increase.
