Abstract :
General AVP (adaptive voltage position) design approach by close loop output impedance analysis is discussed. Based on the analysis, a novel VRM control scheme with direct load current feedback instead of traditional inductor current feedback is introduced. Simulation results and hardware testing demonstrate the good performance of the proposed VRM control.
