FIELD: power conversion. SUBSTANCE: device has transformer which secondary winding 1 is connected to star connection and to alternating current output terminals of power bridge rectifiers. Common point of anodes of gates 3, 5, 7 and 9, 11, 13 of each rectifier is connected to anode of first controlled gate 18 (20) to anode of first diode 22 (24) and first output terminal for connection of loading. Common connection point of cathodes of bridge gates 2, 4, 6 and 8, 10, 12 is connected to cathodes of second controlled gate 19 (21), cathode of second diode 23 (25) and to second output terminal. One terminal of capacitor filter having circuit of two capacitors 14, 15 (16, 17), which are connected in series, is connected to cathode of first controlled gate 18 (20) and to anode of second diode 23 (25). another terminal of the capacitor filter is connected to anode of second controlled gate 19 (21) and to anode of first diode 22 (24). Each charging source 26 (27-29) is connected in parallel to one capacitor of capacitor filter, common point connecting capacitors of capacitor filters is connected to common point of star connection of secondary winding through chokes 30, 31. controlled gates are by-passed by diodes 34-37 which are connected in opposing. EFFECT: simplified design, increased functional capabilities, decreased weight and size, decreased cost, increased reliability, increased capabilities for use in high-power devices. 2 cl, 1 dwg
