Power supply with short circuit protection

Claim 1

A CIRCUIT FOR DISABLING A POWER SUPPLY ON THE OCCURRENCE OF A SHORT CIRCUIT COMPRISING IN COMBINATION: A SATURABLE-CORE REACTOR HAVING A LOAD WINDING, A COMPENSATING WINDING, AND AN OUTPUT WINDING; A D.C. POWER SUPPLY; AN A.C. POWER SUPPLY; A LOAD, SAID LOAD AND SAID LOAD WINDING FORMING A SERIES D.C. CURRENT PATH WITH SAID D.C. POWER SUPPLY; GATING MEANS INTERPOSED IN THE SERIES PATH OF SAID LOAD FOR ELECTRICALLY DISCONNECTING SAID D.C. POWER SOURCE FROM SAID LOAD; COMPENSATING MEANS FORMING A SERIES D.C. CURRENT PATH WITH SAID COMPENSATING WINDING AND ALSO FORMING A PARALLEL D.C. CURRENT PATH WITH SAID LOAD WINDING SO AS TO NORMALLY ESTABLISH A DE-SATURATED CONDITION IN SAID SATURABLE-CORE REACTOR; AN OUTPUT WINDING LOAD MEANS, SAID LOAD MEANS AND SAID OUTPUT WINDING FORMING A SERIES A.C. CURRENT PATH WITH SAID A.C. POWER SUPPLY, SUCH THAT AN INCREASE IN SAID D.C. LOAD CURRENT TENDS TO SATURATE SAID SATURABLE-CORE REACTOR, DECREASING THE FLOW OF COMPENSATING CURRENT AND INCREASING THE FLOW OF A.C. CURRENT THROUGH SAID OUTPUT WINDING SERIES CURRENT PATH; MEANS, ENERGIZED BY THE INCREASED A.C. CURRENT FLOW THROUGH SAID OUTPUT WINDING PROVIDING A TEMPORARY ACTUATING SIGNAL; AND CONTROL MEANS RESPONSIVE TO SAID TEMPORARY ACTUATING SIGNAL PROVIDING A GATING SIGNAL TO SAID GATING MEANS SO AS TO EFFECTIVELY DISCONNECT SAID D.C. POWER SUPPLY FROM SAID LOAD.
