RECTIFIER Russian patent published in 1994 - IPC

FIELD: electric engineering. SUBSTANCE: device has single-phase power transformer having main and additional secondary winding parts which are connected in series and aiding. Working set of rectifying cells 4-7 is made as single-phase bridge joint and its input is connected to main part of secondary winding. Voltage addition set has two rectifying cells 8 and 9 connected in series. Voltage addition set is connected to terminal of additional part of secondary winding through commutator 10. Control input of commutator is connected to output of control unit 11. Outputs of working and voltage addition sets are connected to loading 12. In addition device has variable capacitor 13 and resistor 14 which are connected in parallel to commutator 10. Operations of working and voltage addition sets of rectifying cells are balanced due to phase shift between voltages which supply rectifying sets. EFFECT: increased functional capabilities. 3 dwg
