Abstract :
This paper presents a general small-signal model of paralleled DC/DC modules with current sharing control. With this general small-signal model, the control mode inside each single DC/DC converter doesn´t need to be considered any more, hence the analysis on small-signal stability and output impedance can be simplified. A design example of two 1 V/20 A parallel modules is presented and experimental results verify the performance of current sharing
