Abstract
In an auxiliary-voltage DC source for supplying an electric circuit and, more particularly, one at a high potential in an electron gun without an isolation transformer, the primary winding of a current transformer is located in an alternating-current section of the electric circuit. The current transformer has at least one secondary winding which is connected through a rectifier to a parallel regulator for providing the auxiliary-voltage.
