Average Current Mode Control of Switching Power …
APPLICATION NOTEA verage Current Mode Controlof Switching Power SuppliesLloyd DixonAbstractCurrent mode Control as usually implementedin Switching Power supplies actually senses andcontrols peak inductor Current . This gives rise tomany serious problems, including poor noiseimmunity, a need for slope compensation, andpeak-to- Average Current errors which the inherent-ly low Current loop gain cannot correct. Averagecurrent mode Control eliminates these problemsand may be used effectively to Control currentsother than inductor Current , allowing a muchbroader range of topological PerspectiveCurrent mode Control is a two-loop systemas shown in the simple example of Fig. 1. Theswitching Power supply inductor is hidden within the inner Current Control loop. Thissimplifies the design of the outer voltage con-trol loop and improves Power supply perfor-mance in many ways, including better objective of this inner loop is to controlthe state-space averaged inductor Current , butin practice theinstantaneous peak inductorcurrent is the basis for Control .
