SINGLE-STEP DC/DC TRANSDUCER Russian patent published in 2023 - IPC H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: single-step DC voltage transducers, used in secondary power supply systems for converting, regulating and stabilizing a DC output voltage. The device contains a control key (3) implemented in the form of a field effect transistor (MOSFET), the control electrode of which is connected to a pulse-width controller (10). Power transformer (2), the primary winding (1) of which is connected to a constant input voltage source through a control key (3), and the secondary winding (4) through rectifier diodes (5, 8) is connected to the filter capacitors (6, 7) connected in series parallel to which the load (9) is connected. In the proposed single-step DC/DC transducer, the beginning of the primary winding (1) of the transformer (2) is connected to the positive pole of the input DC voltage source, and the end of the primary winding (1) through a key (3) controlled by a pulse-width controller (10) is connected to its negative pole. With the beginning of the secondary winding (4) of the transformer (2), the anode of the rectifier diode (5) is connected, the cathode of which is connected to one of the terminals of the capacitor (6). The second terminal of the capacitor (6) is connected to the winding end (4). The winding end (4) is connected to one of the terminals of the capacitor (7), the second terminal of which is connected to the anode of the rectifier diode (8), the cathode of which is connected to the beginning of the winding (4). A load (9) is connected in parallel with the capacitors (6) and (7) connected in series.

EFFECT: formation of a constant output voltage from a constant input voltage and a decrease in dynamic losses.
