CONTROL CIRCUIT FOR REDUNDANT POWER SUPPLY BLOCKS IN PARALLEL, IN PARTICULAR FOR THE POWER SUPPLY OF TRANSISTOR-TRANSISTOR LOGIC CIRCUITS

摘要

CONTROL CIRCUIT FOR REDUNDANT POWER SUPPLY UNITS MOUNTED IN PARALLEL AND HAVING AS A COMPARISON QUANTITY FOR THEIR RV ADJUSTMENT CIRCUITS THE VOLTAGE V AT THE LOAD TERMINALS. IN ORDER TO PREVENT A SUBSTANTIAL DROP IN VOLTAGE BETWEEN THE MOVEMENT OR A FAILURE POWER SUPPLY UNIT AND THE TIME ANOTHER POWER SUPPLY TAKES THE RELAY FROM THE FAILING BLOCK, EACH POWER SUPPLY INCLUDES R, V, CS, R, D SUITABLE TO GROW, IN RELATION TO THE NOMINAL VALUE, ITS TENSION SUPPLIED TO THE LOAD, BY A QUANTITY NOT LESS THAN DOUBLE THE MAXIMUM DEVIATION PROVIDED FOR, WHEN ITS CURRENT DROPS BELOW A VALUE I FIXED IN ADVANCE. /P P THE INVENTION IS PARTICULARLY SUITABLE FOR THE SUPPLY OF TTL LOGIC CIRCUITS.
