| Abstract: | In order to predict the dynamic performances of asymmetrical half bridge converter correctly,to design the current-sharing circuit reasonably and to realize the ballanced load-sharing of paralleling asymmetric half bridge converter,a small-signal model of the paralleling asymmetrical half bridge converter is established based on the theory of small-signal analysis.Then,the design points of the automatic current-sharing control circuit are analyzed.The established model is finally adopted to setup a prototyp... |
