Abstract
A flyback transformer includes a high voltage winding with a first rectifier coupled to the high voltage lead and a second rectifier coupled to the ground return lead. The rectifiers are poled in the same direction to conduct beam current and block the DC current path in the winding during the trace interval. The distributed capacity forms a capacitive voltage divider and developes an intermediate DC voltage in the high voltage winding. The intermediate DC voltage developed at an intermediate AC null terminal of the high voltage winding is selectively adjusted by structure which is selectively capable of adding sufficient distributed capacity to appropriately change the capacitive voltage division ratio.
