Abstract:
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 each said Buck converter circuit in interleaved fashion to produce a controllable pulse across said load, and wherein said synchronization controller comprises an oscillator responsively enabled via an on/off command signal; a flip flop connected to an output of said oscillator, said flip flop including dual outputs; and a dual one-shot connected to said dual outputs of said flip flop for generating dual interleaved synchronization signal outputs to said two Buck converters; f. wherein said first and second Buck converters are arranged such that a unidirectional current pulse is generated across said load; and, g. wherein each said Buck converter circuit is connected to a common load ground and each said Buck converter circuit includes an isolated transistor driver.
