FIELD: power converters. SUBSTANCE: method involves generation of two pairs of pulse sequences which are shifted with respect to each other by half period, measurement of output current of pulse secondary power supply, comparison of measured output current to given level, detection of mismatch signal, use of received pairs of pulse sequences for control of power transistors of two single-cycle bridge converters which are connected in parallel to output. In addition method provides control by means of variation in duration of pulses of all sequences in order to change ratio of duration of power accumulation and storage processes in magnetic field of choke transformers under constant total duration of said processes which is equal to half period. Duration of processes of power transmission to load circuit (or return to primary power supply in load circuit mode x. x) is kept constant and is equal to half of period. EFFECT: increased efficiency of control in stabilization mode of output current including variation in load from idle state to short circuit. 2 dwg |
