Abstract
Means for achieving square wave charging of pulse forming networks in line ype pulsers which include parallel pulse forming networks with charging inductors connected between the PFNs. The cumulative value of the distributed inductance of the charging inductors is chosen so that when combined with the total capacitance of the PFNs, the charging network pulsewidth equals the interpulse period.
Claims9
In a pulse generating circuit for supplying pulses to a load and having a plurality of parallel energy storage networks including capacitance means adapted to be charged from a power source through charging inductor means and subsequently discharged through output means coupled to said load and a first storage network connected to said power source through a first charging inductor, the improvement comprising, a second energy storage network, and a second charging inductor connected in series between said second energy storage network and said first charging inductor, said charging inductors providing constant current charging for said energy storage networks and having a cumulative distributed inductance value which when combined with the total capacitance of said energy storage networks provides an output pulse to said load having a pulsewidth equal to the interpulse period between consecutive discharges.
