A method for feeding DC power to an amplifier module for a pulsed load (3), eg an antenna array, comprising the steps of
- providing current pulses (6) from a DC power supply (1);
- charging a capacitor configuration (4) in the amplifier module;
- providing an output voltage (U out ) via a voltage regulated power supply; and
- feeding current pulses (2) to said load from said capacitor configuration. The method is especially characterized by the further steps of
- determining an output current (I out ) pulse (2) configuration appearing during feeding the load from said configuration (4);
- providing a pulsed input current (I in ) from said DC power supply (1) based upon the determined output pulsed current;
- limiting the maximum current level (6') of the input current pulses (6) to a predetermined level by, inter alia, a control and pulse shaping circuit (8) to be substantially lower compared to the peak current (2') of said output current pulses (2). The present invention also relates to a device for feeding DC power. |
