in Fig. 2(a) can be considered as voltage sources, generating
voltage VAN and VBN . Hence, regardless of the conversion
structure, this power converter block can be simplified into the
equivalent circuit which consists of VAN and VBN as shown
in Fig. 2(b) [30], [31]. The leakage current is thus a function
of VAN ,VBN , grid voltage, filter inductance, and stray capacitance.
