MAGNETICALLY COUPLED SINGLE-CYCLE CONSTANT VOLTAGE CONVERTER Russian patent published in 2024 - IPC H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: magnetically coupled single-cycle constant voltage converter relates to electrical engineering and can be used to convert, control and stabilize constant output voltage, which is 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 the input constant voltage source, and the end of primary winding 1 is connected through power control key 3 to the negative pole of the input constant voltage source, which forms a common bus. Beginning of first secondary winding 4 is connected to the anode of first rectifier diode 5, the cathode of which is connected to the first output of capacitor 6, the second output of which is connected to the end of secondary winding 4. Cathode of second rectifying diode 7 is connected to the end of secondary winding 4 of transformer 2, and the anode to the first output of second capacitor 8, the second output of which is connected to the beginning of secondary winding 4. End of second secondary winding 9 is connected to the anode of third diode 10, the cathode of which is connected to the first output of capacitor 11, the second output of which is connected to the beginning of secondary winding 9. Cathode of fourth rectifier diode 12 is connected to the beginning of winding 9 of transformer 2, and the anode is connected to the first output of capacitor 13, the second output of which is connected to the end of winding 9. Common point of connection of diode 7 and capacitor 8 is connected to common point of connection of diode 10 and capacitor 11, and between common points of connection of diode 5 and capacitor 6, diode 12 and capacitor 13 is connected filter capacitor 14 with parallel connected load 15.

EFFECT: generation of constant output voltage from constant input voltage, reduction of static and dynamic losses.
