Abstract: The invention relates to a method and a system for providing current from a DC power supply to pulsed loads in an array. The array comprises at least two electronic units. Each electronic unit comprises a regulator connected to an energy storage, to a pulsed load and to a charge control unit. The charge control unit is arranged to control the supply of DC current to the pulsed load connected to the electronic unit. 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, starting the selected charge control sequence, starting the pulse load pattern, 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.

Abstract: The present invention relates to a radar system for a vehicle, a method for controlling a radar system, a computer program product, and a vehicle comprising such a radar system. The radar system comprises an antenna arrangement for transmitting and/or receiving electromagnetic waves, a power supply connected to the antenna arrangement, the power supply being arranged to supply the antenna arrangement with operating power. The radar system further comprises an antenna controller connected to the antenna arrangement, the antenna controller being configured to control an operation of the antenna arrangement. The radar system also comprises an auxiliary power source connectable to the antenna arrangement for supplying the antenna arrangement with supplementary operating power so to increase an output power of the antenna arrangement, and a boost controller connected to the auxiliary power source and to the antenna controller, the boost controller being configured to connect and disconnect the auxiliary power source to/from the antenna arrangement. Hereby presenting a radar system capable of increasing the maximum range of the antenna arrangement during an arbitrary period of time without suffering from too heavy penalties in terms of increased weight or cost.
