A power converter and management system for providing energy to a pulsating load, comprising: up-converting means for converting a primary battery power source voltage to a higher voltage on a storage capacitor, thereby storing energy in said storage capacitor for providing energy to a single pulse load of said pulsating load; limiting means for limiting a current drawn by said up-converting means, from said primary power source voltage, to a maximum current setting; down-converting means for converting said storage capacitor voltage to a lower operating voltage, which lower operating voltage is provided to said single pulse load of said pulsating load thereby consuming energy stored in said storage capacitor and thereby leaving an inevitable residual storage voltage at said storage capacitor, characterized by energy optimizer means comprising: - voltage measuring means arranged for measuring said residual storage voltage at said storage capacitor, i.e. after energy in said storage capacitor has been consumed by said single pulse load of said pulsating load; - comparing means arranged for comparing said measured residual storage voltage with a predefined target voltage thereby defining a delta voltage; - control means arranged for controlling said up-converting means such that the amount of energy to be stored in said storage capacitor is controlled in such a way that said delta voltage is lowered for a subsequent pulse of said pulsating load. up-converting means for converting a primary battery power source voltage to a higher voltage on a storage capacitor, thereby storing energy in said storage capacitor for providing energy to a single pulse load of said pulsating load; limiting means for limiting a current drawn by said up-converting means, from said primary power source voltage, to a maximum current setting; down-converting means for converting said storage capacitor voltage to a lower operating voltage, which lower operating voltage is provided to said single pulse load of said pulsating load thereby consuming energy stored in said storage capacitor and thereby leaving an inevitable residual storage voltage at said storage capacitor, characterized by energy optimizer means comprising: - voltage measuring means arranged for measuring said residual storage voltage at said storage capacitor, i.e. after energy in said storage capacitor has been consumed by said single pulse load of said pulsating load; - comparing means arranged for comparing said measured residual storage voltage with a predefined target voltage thereby defining a delta voltage; - control means arranged for controlling said up-converting means such that the amount of energy to be stored in said storage capacitor is controlled in such a way that said delta voltage is lowered for a subsequent pulse of said pulsating load. - voltage measuring means arranged for measuring said residual storage voltage at said storage capacitor, i.e. after energy in said storage capacitor has been consumed by said single pulse load of said pulsating load; - comparing means arranged for comparing said measured residual storage voltage with a predefined target voltage thereby defining a delta voltage; - control means arranged for controlling said up-converting means such that the amount of energy to be stored in said storage capacitor is controlled in such a way that said delta voltage is lowered for a subsequent pulse of said pulsating load.
