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

FIELD: electrical engineering.

SUBSTANCE: single-cycle DC voltage converter with direct and 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, 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, 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 secondary winding 8 is connected to the anode of first rectifying diode 9, the cathode of which is connected to the first output of the capacitor of filter 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 beginning of secondary winding 8 of transformer 2, and the anode to the first output of the second capacitor of filter 12, the second output of which is connected to the end of secondary winding 8. Load 13 is connected between two filter capacitors 10, 12 connected in series.

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