FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to single-cycle constant voltage converters, and can be used in secondary power supply systems for conversion of constant output voltage level, galvanically separated from input constant voltage. Device comprises transformer 2, beginning of primary winding 1 of which is connected to positive pole of input source of constant voltage, and end of primary winding 1 through control key 1 to its negative pole. Parallel to primary winding 1 of transformer 2 there is a passive clamping element made up of series-connected diode 5 and capacitor 4 with parallel connected resistor 6. Beginning of first secondary winding 7 of transformer 2 is connected to the anode of first rectifying diode 8, the cathode of which is connected to one of the leads of capacitor 9, the second lead of which is connected to the end of winding 7. Common point of connection of cathode of rectifier diode 8 with capacitor 9 is connected to end of second secondary winding 10, which beginning is connected to the first output of filter capacitor 11 with parallel connected load 12, the second output of which is connected to the common point of connection of the beginning of secondary winding 7 with the anode of rectifying diode 8.
EFFECT: formation of required level of constant output voltage from constant input voltage, reduction of static and dynamic losses.
