FIELD: electrics.
SUBSTANCE: converter includes power transformer with primary winding connected over adjustment transistor to converter inputs, secondary winding connected over rectifying diode and output LCD filter to converter outputs, and demagnetising winding connected over diode to converter output, control unit with output connected to control circuit of adjustment transistor, and feedback circuit. Power transformer features additional winding included in feedback circuit, with one winding end connected over rectifying diode to control unit input and the other end connected to converter input. Coil ratio of primary winding to demagnetising winding is defined by expression: n1/np≥(Uin.min /Uout)·[γ/(1-γ)], where n1 is coil number in primary winding; np is coil number in demagnetising winding, Uin.min is minimum value of input voltage variation range; Uout is stabilised output voltage; γ is ratio of open state duration for adjustment transistor topen to impulse recurrence period T.
EFFECT: improved reliability reduced construction dimensions and cost without change to core magnetisation tolerance condition.
