Abstract :
A method is proposed to quantitatively analyze performance degradation of DC-DC power converters in distributed power systems. The interaction among modules is analyzed in terms of loop gain and impedance ratio measurements. The approach is to predict performance changes in loop gains of converters. Theoretical and step-by-step experimental methods are proposed. Experiments support the accuracy of the predictions
