SINGLE-ENDED REVERSIBLE DC VOLTAGE CONVERTER Russian patent published in 2007 - IPC H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: proposed single-ended reversible DC voltage converter incorporating output voltage feedback has input filter, electronic power switch, power transformer, single-ended output filter-rectifier, and control circuit that functions to close and open electronic power switch in response to feedback voltage generated by feedback circuit; the latter has auxiliary electronic switch whose control input is connected to additional secondary winding of power transformer, and isolating transformer whose primary winding is shorted out by demagnetizing component and connected through auxiliary electronic switch to output leads of converter; secondary winding is connected through additional single-ended filter-rectifier to feedback input of control circuit.

EFFECT: ability of affording electric isolation of input and output circuits dispensing with optocoupler or double-ended converter.
