Abstract
A power system for powering a pulsed load that intermittently delivers current pulses can include: an energy reservoir; a first DC-DC converter having an input that receives an input voltage and an output coupled to the energy reservoir; a second DC-DC converter having an input coupled to the energy reservoir and an output couplable to the pulsed load; and control circuitry that operates the first DC-DC converter to charge the energy reservoir from a minimum or valley voltage to a maximum or peak voltage during a charging window just prior to a current pulse of the pulsed load so that the first DC-DC converter is at or near its maximum output current at a beginning of the current pulse of the pulsed load.
