TRACK CIRCUIT POWER SOURCE Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: power source has four inverse conductivity transistors 5, 6 and 7, 8 which bases are connected in parallel and to first and second outputs of transformer 4 through resistors 13 and 15 respectively. Collectors with diodes 9,10 and 11, 12 connected in series are also connected in parallel and to the first and second phase comparison circuits respectively and to one output of track frequency converter 2 through first and second inputs of commutator 3. The emitters of all transistors are connected to interconnected middle output of the winding of transformer 4 and the other output of track frequency converter 2 connected to commutator 3. EFFECT: improved structure. 1 dwg
