D C/D C CONVERTER Russian patent published in 1994 - IPC

FIELD: sources of secondary power supply. SUBSTANCE: D C/D C converter is intended for increased efficiency and expanded field of application thanks to insertion into rack of current transformers of two circuits of diodes connected in series, of two supplementary transistor keys and of four diodes. Inserted elements are so connected that emitter commutation and current-proportional control over power transistors working in accord with circuit with common base are realized in static converter. Paths of switching over of power transistors do not fall outside the limits of safe operation and through currents are eliminated. Apart from this specified principle of functioning makes it possible to use at the same transistors with lower speed of response. EFFECT: increased efficiency, expanded field of application. 1 dwg
