	<span lang=\"EN-US\">Inductively coupled power transfer systems
(ICPT) are becoming ubiquitous in industry. Many such systems are excited with single
or multi-phase input current. This leads to increased complexity in comparing such
systems when solely using the magnetic frequency analysis. This paper utilizes modern
finite element method analysis software to propose a novel software methodology
for the numerical comparison of single and two phase ICPT systems as demonstrated
on a three dimensional (3D) battery charging system. The sinusoidal magnetic frequency
response of a single phase system is compared to the magnetic transient response
of a multi-phase current system by use of a novel software methodology proposed
in this paper. This consists of a transient response analysis to determine compute
the resulting magnetic re</span><span lang=\"EN-US\">sponse over the duration of an input current period on the two phase system.
The resulting non-sinusoidal response is then integrated over a whole period to
extract the root-mean-square value for comparison with that of a single</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\">phase system across a 3D cubic power zone.</span><span lang=\"EN-US\"><o:p></o:p></span>
