Abstract

The introduction of the beam index cathode ray tube (CRT) as an airborne pilot display unit imposes tight performance requirements on the associated high voltage power supply (HVPS). Previous HVPS technology produced upwards of 25,000 Vdc (25 Watts) anode potential with plus or minus 0.1% regulation allowance (100 Vpk instantaneous deviation). Beam index technology requires a HVPS of higher anode potential and 100% tighter regulation. This and other demanding electrical requirements of beam index CRT HVPS are presented in this paper, together with design approaches to meet them. The HVPS output power density, thermal stability, and dynamic focus performance were all improved.
