1. A method for providing DC current from a DC power supply to pulsed loads in an array of electronic units, wherein the array comprises at least a first and a second electronic unit, where each electronic unit comprises a regulator connected to an energy storage and a pulsed load, where the regulator is further connected to a charge control unit, where the charge control unit is arranged to control the supply of DC current to the pulsed load connected to the electronic unit, wherein the method comprises:
selecting a pulse load pattern for the pulsed loads,
selecting a charge control sequence by a control system connected to the electronic units and the DC power supply,
instructing the charge control unit by the control system to start the selected charge control sequence,
starting the pulse load pattern,
wherein the method comprises:
synchronizing the pulsed loads in the electronic units to turn on and turn off simultaneously,
providing DC current from the DC power supply to each electronic unit at different times according to the selected charge control sequence set by the charge control unit, the charge control unit thereby controlling how and when each regulator provides current to each energy storage.
