In this paper double averaging method is used for describing the model of this converter. By this model we would be able to explain the low frequency dynamics of the system and identify stability boundaries according to circuit parameters and also nonlinear phenomena of this converter are detected. | Cite this Reference: Mehrnoosh Vatani, Soodabeh Soleymani and Mehrdad Ahmadi Kamarposhti, 2013.
