Abstract
A vertical drive circuit is provided for supplying a current to a deflection yoke in a CRT display. The vertical drive circuit provides a first voltage which when applied to a deflection yoke will cause the electron beam to be deflected from the top of the screen to the bottom. A retrace circuit supplies a second voltage which will cause the beam to be returned to the top of the screen at the conclusion of a complete vertical scan.
