dc.description.abstractAESA radar systems are heavily pulsed and often equipped with large capacitor banks to be able to supply the load with enough current and to not put extra stress on the supply. The goal of this thesis was to implement a digital control for the existing stepdown converter as well as implementing a digitally controlled active filter in parallel with the existing step-down converter. The developed filter was able to supply the load fast enough without using the extra capacitor bank normally used. The goal was also to have close to zero amps in uctuations on the input bus. The obtained end result was uctuations of about 40 mA compared to 60 mA in the thesis "Digitally Controlled Active Power Filter" including the capacitor bank. The maximum output voltage diversion was 300 mV during the pulse and 40 mV in steady state. Also the efficiency was improved to 66% when comparing the complete system with the system in the former work [1].
