Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
160 words
A VOLTAGE SHARING CIRCUIT FOR USE WITH A POSITIVE VOLTAGE POTENTIAL, A REFERENCE POTENTIAL AND A PLURALITY OF SERIALLY CONNECTED SEMICONDUCTOR CURRENT CONTROLLED SWITCHES, EACH OF SAID SWITCHES HAVING AN ANODE, A CATHODE, AND A GATE, THE CATHODE OF EACH OF SAID SWITCHES BEING CONNECTED TO THE ANODE OF THE NEXT OF SAID SWITCHES, BEING CATHODE OF A LAST OF SAID SWITCHES BEING CONNECTED TO THE REFERENCE POTENTIAL, SAID CIRCUIT; COMPRISING A PLURALITY OF RESISTOR, A FIRST OF SAID RESISTORS BEING CONNECTED FROM THE ANODE OF A FIRST OF SAID SWITCHES TO THE CATHODE OF SAID FIRST OF SAID SWITCHES, EACH OF THE REMAINDER OF SAID RESISTORS BEING CONNECTED FROM THE GATE OF ONE OF SAID SWITCHES TO THE CATHODE OF THE NEXT OF SAID SERIALLY CONNECTED SWITCHES, THE ANODE OF A FIRST OF SAID SWITCHES BEING COUPLED TO SAID POSITIVE POTENTIAL, WHEREBY A CHANGE IN VOLTAGE ACROSS SAID SERIALLY CONNECTED SWITCHES IS PREVENTED FROM FIRING SAID PLURALITY OF SWITCHES.
Claim 2
Dependent Claim
