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

FIELD: electrical engineering.

SUBSTANCE: magnetically coupled single-cycle constant voltage converter with voltage doubling at load relates to electrical engineering and can be used for conversion, control and stabilization of constant output voltage, which is galvanically separated from input constant voltage. Device comprises transformer 2, the beginning of first primary winding 1 of which is connected to the positive pole of the input constant voltage source, and the end of first primary winding 1 is connected to the anode of diode 3, the cathode of which is connected through first capacitor 4 to the negative pole of the input constant voltage source, which forms a common bus. Beginning of second primary winding 5 of transformer 2 is connected to the common point of connection of the cathode of diode 3 and capacitor 4, and the end of the winding is connected to the common bus through power control key 6. Between the end of second primary winding 5 and the anode of diode 3 second capacitor 7 is connected. Beginning of first secondary winding 8 is connected to the anode of first rectifying diode 9, the cathode of which is connected to the first output of capacitor 10, the second output of which is connected to the end of secondary winding 8. Cathode of second rectifying diode 11 is connected to the end of secondary winding 8 of transformer 2, and the anode to the first output of second capacitor 12, the second output of which is connected to the beginning of secondary winding 8. Between two capacitors 10, 12 opposite to first secondary winding 8 there is second secondary winding 13 is connected with series-connected filter capacitor 14, in parallel to which load 15 is connected.

EFFECT: generation of constant output voltage from constant input voltage with voltage doubling at the load, exclusion of L-shaped smoothing LC-filter, to which the load is connected, reduction of static and dynamic losses.
