DEVICE FOR CHARGING CAPACITIVE STORAGE Russian patent published in 1994 - IPC

FIELD: pulse current sources. SUBSTANCE: device has d. c. voltage supply, circuit formed by the first, the second and the third chokes connected in series, the first diagonal of capacitive bridge and thyristor storage, the first capacitor connected with outputs of the source through the first choke, the second capacitor connected across a diagonally opposite pair of junctions of the thyristor bridge, two diodes connected in parallel to the first and the second chokes opposite in relation to thyristors of the bridge. Additional thyristor is connected between one of the outputs of the second diagonal of the bridge and negative terminal of the source directly or through additional capacitor. Moreover, common wires of the additional thyristor and capacitor may be connected to outputs of the potentiometer which is connected with outputs of d. c. voltage source. EFFECT: improved efficiency of operation. 3 cl, 3 dwg
