The stability of the DC power electronics based power distribution systems is a significant design consideration because of the potential for negative impedance induced instabilities. In this paper, pulse adjustment technique, a novel digital control technique to control DC-DC converters loaded by constant power loads (CPLs) is introduced. This novel digital control treats converter as a digital system and regulates output voltage with the help of two predefined state variables. This method uses high-power and low-power duty cycles instead of traditional PWM, to regulate the output voltage of converter. The constant power load behaviour is valid up to a certain frequency. An ideal constant power load is somehow the worst case, and for this reason the studies are done in the worst case. For transient situations we proposed a modified version of pulse adjustment controlling method with variable high-power duty cycle which can stabilize the DC system. Besides, pulse adjustment technique with variable high-power duty cycle can be modified to achieve efficient line regulation
