Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
145 words
IN A POWER SUPPLY HAVING A SERIES REGULATOR WHICH IS RESPONSIVE TO THE VOLTAGE APPEARING ACROSS A LOAD CIRCUIT, A RESISTOR IN SERIES WITH SAID LOAD CIRCUIT TO PRODUCE A FIRST VOLTAGE THAT IS RELATED TO THE CURRENT IN SAID LOAD CIRCUIT, MEANS CONNECTED TO SAID REGULATOR FOR PRODUCING A SECOND VOLTAGE THAT IS RELATED TO THE VOLTAGE APPEARING ACROSS SAID SERIES REGULATOR, A GAIN ELEMENT CONNECTED TO CONTROL THE IMPEDANCE OF SAID REGULATOR AND CONNECTED TO RECEIVE THE FIRST VOLTAGE, SAID GAIN ELEMENT BECOMING EFFECTIVE TO INCREASE CONTINUALLY THE IMPEDANCE OF SAID REGULATOR WHEN THE FIRST VOLTAGE EXCEEDS A PREDETERMINED VALUE, AND NORMALLY NON-CONDUCTIVE MEANS CONNECTED TO SAID GAIN ELEMENT FOR APPLYING THERETO SAID SECOND VOLTAGE, SAID NON-CONDUCTIVE MEANS BECOMING CONDUCTIVE FOR RENDERING SAID GAIN ELEMENT EFFECTIVE FURTHER TO INCREASE CONTINUALLY THE IMPEDANCE OF SAID REGULATOR WHEN THE SECOND VOLTAGE EXCEEDS A PREDETERMINED VALUE.
