FORWARD SINGLE-STROKE CONSTANT VOLTAGE CONVERTER WITH ADJUSTABLE INPUT VOLTAGE Russian patent published in 2025 - IPC H02M3/335 

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, control and stabilization of constant output voltage, galvanically separated from input constant voltage. Device comprises transformer 2, the beginning of primary winding 1 of which is connected to the positive pole of first capacitor 3, and the end of primary winding 1 through control key 4 to its negative pole and the negative pole of the input constant voltage source. In parallel to primary winding 1 of transformer 2, a clamping element is connected, made up of series-connected rectifier diode 5 and second capacitor 6, connected by the cathode of diode 5 to the positive pole of first capacitor 3, and the anode to the first pole of second capacitor 6, which second pole is connected to common point of connection of end of primary winding 1 with control key 4. Common point of connection of the anode of rectifying diode 5 with second capacitor 6 is connected to the first output of linear inductance 7, the second output of which is connected to the positive pole of the input constant voltage source. Beginning of secondary winding 8 of transformer 2 is connected to the anode of rectifying diode 9, the cathode of which is connected to one of the outputs of the capacitor of filter 10 with parallel connected load 11, the second output of which is connected to the end of winding 8.

EFFECT: formation of required level of constant output voltage from constant input voltage, reduction of static and dynamic losses.
