It is worth highlighting that the model in Fig. 2(c) has been
commonly used for describing the common-mode behavior of
the conventional full-bridge (H4) topology. However, due to
the generality of the model, it is obvious that the model is
valid for other topologies discussed here, apart from H4. As a
matter of fact, the same model has been used to analyze the
common-mode behavior of various transformerless converter
topologies [16], [21], [29], [30]. However, since different topology
has different VAN and VBN , the expressions for VCM
and VDM will differ from one another, which yield different
