摘要：
A general model of paralleled converter with active current sharing is used to discuss the stability based on the Thevenin source model. In the model, the current sharing loop and interface stability are separately considered in order to guarantee the system stability. The analysis only focuses on identical converters case for simplicity. An example is given to illustrate the method to design current sharing circuit and the influence of the number of paralleled converters is discussed. A prototype is tested to verify the model.
