Abstract
A fly-back type power supply includes a transformer, the primary winding of which is periodically connected to a DC source to establish current through such winding, When this current increases to a predetermined optimum value, the current flow through the primary winding is interrupted for producing collapse of the transformer's magnetic field and generation of an output in the transformer's secondary windings. The frequency at which the primary is periodically connected to the DC source is controlled by a secondary output voltage such that the frequency is increased when such output voltage tends to decrease. A plurality of secondary windings are each connected to a rectifier and filter capacitor combination, wherein the filter capacitors are coupled in series for production of a high voltage output.
