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

FIELD: electricity.

SUBSTANCE: single-cycle constant voltage converter with direct transfer of energy to load relates to electrical engineering and can be used for conversion, control and stabilization of constant output voltage, 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, 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 secondary winding 8 is connected to the anode of 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. Load 11 is connected in parallel to filter capacitor 10.

EFFECT: generation of constant output voltage from constant input voltage with transfer of energy to load on direct line, id est on the time interval of the on state of the power control switch, exclusion of the L-shaped smoothing LC-filter, to which the load is connected, reduction of static and dynamic losses.
