OUTPUT CIRCUIT OF PULSE VOLTAGE CONVERTER, METHOD OF ITS GALVANIC ISOLATION, PULSE CONVERTER OF VOLTAGE AND PULSE SOURCE OF SUPPLY Russian patent published in 2012 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: inventions relate to equipment of pulse voltage converters and may be used in design of their galvanically isolated output circuits. In an output circuit of a pulse voltage converter, comprising a device of galvanic isolation with a rectifier and a smoothing filter, the rectifier is connected to a key cascade via two or more separating capacitances, and a useful load is connected to the rectifier via two or more separating inductances. In the method for galvanic isolation suppression of DC current and currents of industrial frequencies is carried out using reactive resistances of a capacitance nature, and suppression of currents of internal frequencies of a pulse voltage converter is carried out using reactive resistances of an inductive nature. In a pulse voltage converter and in a pulse supply source, key cascades and output circuits are arranged as capable of implementing of previous technical solutions.

EFFECT: development of technical solutions for galvanic isolation of an output circuit of a pulse supply source and/or a pulse voltage converter, comprising circuits of useful load, differing with simplicity, compactness, reliability and increased efficiency, in contact with equipment, which has an electric contact with useful load circuits, both for good or faulty pulse source of supply and/or a pulse voltage converter.
