Generator field coil energizing reversing circuit
Abstract
Abstract A GENERATOR FIELD COIL ENERGIZATION REVERSING CIRCUIT FOR USE WITH A GENERATOR OF THE TYPE HAVING A FIELD COIL AND IN COMBINATION WITH AN ASSOCIATED POTENTIAL REACHING THE TYPE RESPONSIVE TO GENERATOR OUTPUT POTENTIAL REACHING A PREDETERMINED MAGNITUDE TO OPERATE AN ASSOCIATED CONTROL SWITCH TO THE ELECTRICAL CIRCUIT OPEN CONDITION. THE GENERATOR FIELD IS CONNECTED ACROSS A SOURCE OF DIRECT CURRENT GENERATOR FIELD COIL ENERGIZING POTENTIAL IN ONE POLARITY RELATIONSHIP THROUGH THE CURRENT CARRYING ELECTRODES OF A FORWARD DIRECTION GENERATOR FIELD COIL SWITCHING TRANSISTOR BEING CONDUCTIVE ONLY WHILE THE CONTROL SWITCH IS CONDUCTIVE, AND IN A REVERSE POLARITY RELATIONSHIP THROUGH THE CURRENT CARRYING ELECTRODES OF A REVERSE DIRECTION GENERATOR FIELD COIL SWITCHING TRANSISTOR WHICH IS RESPONSIVE TO CONDITIONS OF GENERATOR OUTPUT OVER-POTENTIAL TO BECOME CONDUCTIVE.
