The invention relates to electrical engineering, in particular to single-ended DC voltage converters, and can be used in secondary power supply systems to convert, regulate and stabilize the DC output voltage. The purpose of the invention is to generate a constant output voltage from a constant input voltage and reduce dynamic losses. The device contains a control switch 3, implemented in the form of a field-effect transistor (MOSFET), the control electrode of which is connected to a pulse width controller 10. A power transformer 2, the primary winding 1 of which is connected via a control switch 3 to a constant input voltage source, and the secondary winding 4 is connected via rectifier diodes 5,8 to series-connected filter capacitors 6,7, in parallel to which the load 9 is connected. In the proposed single-ended DC converter, the beginning of the primary winding 1 of transformer 2 is connected to the positive pole of the input DC voltage source, and the end of the primary winding 1 is connected to its negative pole via a switch 3 controlled by a pulse width controller 10. The anode of the rectifier diode 5 is connected to the beginning of the secondary winding 4 of transformer 2, the cathode of which is connected to one of the terminals of capacitor 6. The second terminal of capacitor 6 is connected to the end of winding 4. The end of the winding 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. The load 9 is connected in parallel with series-connected filter capacitors 6 and 7.
