Claim 1
Independent Claim
150 words
A PULSE GENERATOR COMPRISING A POWER STORAGE CONDENSER MEANS AND A LOAD CONNECTED IN SERIES; AN INDUCTANCE, A RECTIFIER, AND A FIRST D.C. SOURCE OF PREDETERMINED VOLTAGE CONNECTED IN SERIES AND ACROSS SAID CONDENSER MEANS AND LOAD FOR RESONANTLY CHARGING SAID CONDENSER MEANS TO SUBSTANTIALLY TWICE THE VOLTAGE OF SAID D.C. SOURCE, THE IMPEDANCE OF THE CHARGING CIRCUIT BEING RELATIVELY LOW FOR RAPID CHARGING RATE, SWITCH MEANS CONNECTED ACROSS SAID CONDENSER MEANS THROUGH SAID LOAD, A SECOND ING SAID CONDENSER MEANS THROUGH SAID LOAD, A SECOND D.C. SOURCE CONNECTED ACROSS SAID CONDENSER AND LOAD, THE CIRCUIT OF SAID SECOND D.C. SOURCE HAVING RELATIVELY HIGH IMPEDANCE COMPARED TO THE IMPEDANCE OF SAID CHARGING CIRCUIT AND THE VOLTAGE VALUE OF SAID SECOND D.C. SOURCE BEING RELATIVELY HIGH COMPARED TO THE CHARGE VOLTAGE OF SAID CONDENSER MEANS TO MAINTAIN SUBSTANTIALLY CONSTANT, BETWEEN SUCCESSIVE OPERATIONS OF THE SWITCH, THE CHARGE VOLTAGE OF SAID CONDENSER.
