STABILIZING D C/D C BRIDGE CONVERTER Russian patent published in 1995 - IPC

FIELD: radio electronics. SUBSTANCE: stabilizing D.C./D.C. bridge converter includes closing keys 21, 24, first one placed between power output of first switching key 1 and connection point of diode 13 and resevoir capacitor 12. Control over keys 21, 24 is carried out by modulator 14 of controlling pulses through separated outputs. First switching key 1 and second closing key 24, second switching key 2 and first closing key 21 are controlled by inphase signals having length equal to half-period of working grequency. Signals of control over these pairs of keys are shifted by 180 deg with reference to each other. Two regulating keys 3, 4 are switched over in counterphase relative to each other (each inphase with proper switching key) and are controlled by pulse of changeable length from zero to half-period of working frequency. Switching 1, 2 and regulating 3, 4 keys form bridge fed through reservoir choke 8. Current closing diode 13 and reservoir capacitor 12 are connected in parallel to bridge. EFFECT: enhanced operational reliability and efficiency. 2 dwg
