Abstract

DC generators produce current at very high voltage and the voltage produced may be altered very rapidly to feed a capacitative load such as the anode of a CRT. The colour produced by the phosphor of the CRT varies with changes in the anode voltage. The generator has a large number of DC sources; it has a transformer with a single primary and several secondaries; one for each voltage produced. Several similar circuits may be connected to different secondaries of the transformer. Each circuit contains a pair of transistors connected to further transformers. The end circuit on the last transformer secondary is of simplified pattern with no transformers.
