SECONDARY SOURCE OF SUPPLY Russian patent published in 2012 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: secondary source of supply comprises the first switching element, a control input of which is connected with an output of the switching element control device, inputs of which are connected to outputs of the first secondary winding of a transformer, the first output of the first primary winding of which is connected with the first output of the primary source of supply, and the second output of the first primary winding is connected to the first output of the first switching element, at the same time a load is connected to the second secondary winding of the transformer, additional switching elements, primary windings identical to the first primary winding of the transformer and serially connected capacitors. At the same time the first outputs of all primary windings of the transformer are connected to the first outputs of appropriate capacitors, the second outputs of which are connected to the second outputs of appropriate switching elements, the first outputs of additionally introduced switching elements are connected to the second outputs of additionally introduced primary windings, the second output of the primary source of supply is connected to the second output of the last switching element.

EFFECT: increased reliability of secondary supply source operation.
