Synthesis of averaged circuit models for switched power converters

Averaged circuit models for switching converters are developed using a direct circuit averaging method. The method proceeds in a systematic fashion by determining appropriate averaged circuit elements that are consistent with the averaged circuit waveforms. The averaged circuit models that are obtained are synthesis of the state-space averaged models for the underlying switched circuits. An important feature of the method is that it is applicable to switched circuits whose nonswitch elements may be nonlinear. The results obtained using this method are compared with the results on averaged circuit models available in the literature
