SINGLE-CYCLE CONSTANT VOLTAGE CONVERTER WITH REVERSE TRANSFER OF ENERGY TO LOAD Russian patent published in 2024 - IPC H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: single-cycle constant voltage converter with reverse transfer of energy to 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, 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, 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. End of secondary winding 8 is connected to the anode of rectifying diode 9, the cathode of which is connected to the output of the capacitor of filter 10, with parallel connected load 11, the second output of which is connected to the beginning of secondary winding 8.

EFFECT: generation of constant output voltage from constant input voltage with transfer of energy to load at reverse stroke, id est on time intervals of power control key off state, and exclusion of L-shaped smoothing LC-filter, to which load is connected.
