VOLTAGE CONVERSION DEVICE Russian patent published in 2016 - IPC H02M5/451 H02M5/48 G05F1/147 H01F29/04 

FIELD: electricity.

SUBSTANCE: voltage conversion device with a transformer (12), which, based on input voltage (U_in), is intended to provide output voltage (U_out), comprises an input winding unit (30) and an output winding unit (32) and may operate according to two working modes, which, accordingly, are correlated with a different voltage conversion ratio. One of winding units (30, 32) comprises the first (38) and second winding (40), and one accordingly differing working configuration of windings (38, 40) is correlated with working modes. In order to provide the voltage conversion device of the above type, by means of which the ratio of stray inductances of the transformer may be more accurately set between working modes, it is proposed that the first winding (38) has winding parts (42), which with the parts (44) of the second winding (40) create alternating location.

EFFECT: increased accuracy of determination of ratio of stray inductances of a transformer between working modes.
