Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
134 words
A VOLTAGE REGULATING RECTIFIER CIRCUIT COMPRISING A SATURABLE CORE REACTOR HAVING A POWER WINDING ADAPTED TO SATURATE THE CORE UNDER NORMAL CONDITIONS, A POWER CIRCUIT THROUGH SAID POWER WINDING INCLUDING A RECTIFIER FOLLOWING SAID WINDING AND A D.C. CIRCUIT INCLUDING FILTER MEANS PROVIDING A SUBSTANTIALLY LEVEL D.C. VOLTAGE THROUGHOUT EACH CYCLE FOLLOWING SAID RECTIFIER, MEANS FOR DERIVING AN OUTPUT VOLTAGE ACROSS SAID FILTER MEANS, A CONTROL CIRCUIT INCLUDING A CONTROL WINDING, A SILICON JUNCTION DIODE CONNECTED IN SERIES WITH SAID CONTROL WINDING AND HAVING ITS CATHODE CONNECTED TO THE POSITIVE SIDE OF SAID CONTROL CIRCUIT, MEANS FOR ENERGIZING SAID CONTROL CIRCUIT WITH AT LEAST A PORTION OF SAID OUTPUT VOLTAGE SAID CONTROL CIRCUIT INDUCING A FLUX OPPOSING THE FLUX OF THE POWER WINDING AND REDUCING THE LEVEL OF CORE SATURATION DURING NON-CONDUCTING HALF CYCLES.
