Claim 1
Independent Claim
186 words
AN ALTERNATING CURRENT GENERATING SYSTEM COMPRISING: AN ALTERNATOR HAVING A COMMUTATOR, A MAIN SHUNT FIELD WINDING CONNECTED ACROSS SAID COMMUTATOR, AN AUXILIARY FIELD WINDING AND AN OUTPUT WINDING EXCITED INDEPENDENTLY OF SAID MAIN FIELD WINDING; A PAIR OF INDEPENDENT SATURABLE MAGNETIC CORES EACH HAVING A RESPECTIVE POWER WINDING; A RECTIFIER BRIDGE HAVING A.C. INPUT TERMINALS CONNECTED ACROSS SAID OUTPUT WINDING AND D.C. OUTPUT TERMINALS CONNECTED TO FEED SAID AUXILIARY FIELD WINDING, ALTERNATELY CONDUCTING LEGS OF SAID BRIDGE INCLUDING ONE OF SAID CORE POWER WINDINGS, RESPECTIVELY, TO DEFINE WITH SAID AUXILIARY FIELD WINDING AN EXCITER CIRCUIT HAVING AN IMPEDANCE WHICH VARIES INVERSELY WITH THE SATURATION OF SAID CORES; A CONTROL WINDING FOR DETERMINING THE SATURATION OF SAID CORES; A CONTROL TRANSFORMER HAVING A PRIMARY WINDING IN SERIES WITH SAID OUTPUT WINDING AND HAVING A SECONDARY WINDING; AND A SECOND RECTIFIER BRIDGE HAVING INPUT TERMINALS CONNECTED ACROSS SAID SECONDARY WINDING OF SAID TRANSFORMER AND D.C. OUTPUT TERMINALS CONNECTED TO FEED SAID CONTROL WINDING TO DETERMINE THE DEGREE OF SATURATION OF SAID CORES AND THE EFFECTIVENESS OF SAID EXCITER CIRCUIT IN ACCORDANCE WITH THE LOAD CONDITION OF SAID ALTERNATOR.
