Time averaging equivalent circuit analysis for a class of periodically switching linear network

A unified approach, i.e. the time-averaging equivalent circuit analysis, is proposed for a class of periodically switching linear networks. The distinctive feature of the approach is to replace the pulsewidth modulated switches inside the original network prior to any further treatment, yielding a structure-invariant linear circuit, which can thus be analyzed in a conventional manner. The parameters of the time-averaging equivalent circuit model can easily be determined by the approach without a prior knowledge of the DC solution for the converter. The DC analysis and small-signal analysis can then be performed based on its time-averaging equivalent circuit model.<>
