Appeal 2006-3382
Application 10/461,709
Appellant appeals from a final rejection of claims 1, 2, 4, 5, 7, 8, 14-
22, 28-51, 53-55, and 57-62 under authority of 35 U.S.C. § 134 (2002). The
BPAI has jurisdiction under 35 U.S.C. § 6(b)(2002).
Appellant’s invention relates to a circuit for delivering high power
current pulses to an electronic load in an efficient manner. In the words of
the Appellant:
The present invention comprises a scalable, interleaved pulse forming
converter having 2 Buck switching converter modules each
contributing half to the total load of the circuit. Synchronization
pulses to the two modules are set 180 degrees out of phase of each
other to reduce ripple current. Additional embodiments are also
claimed in which module interleaving may be utilized to further
reduce ripple current and increase power, as well as to electrically
isolate the load from input or battery ground.
Claim 1 and Claim 57 are exemplary and representative:
1. A circuit for providing an electrical pulse to a load, comprising:
a. a first Buck converter circuit;
b. a second Buck converter circuit connected to said first Buck
converter circuit, each said Buck converter circuit adapted to
receive a current command signal for establishing an internal
reference voltage within each said Buck converter circuit;
c. means for applying a voltage across said first and said second
Buck converter circuits;
d. a capacitor connected in parallel with said voltage means for
reducing ripple in said voltage across said first and said second
Buck converter circuits;
e. a synchronization controller operationally connected to each
said Buck converter circuit for initiating electrical pulses in
