Your sample file includes packages which are incompatible with tex4ht and which aren't useful in HTML mode anyway: transparent and pst-pdf. You can enable them only in PDF mode using:
\ifdefined\HCode\else
\usepackage{pst-pdf}
\usepackage{transparent}
\fi
Your document can be compiled without these packages.
There is then question of image inclusion. You use two ways, first is direct PDF inclusion, the second is using TeX files with drawing commands exported by Inkscape.
The first way:
\begin{figure}%
\centerline{\psfig{figure=img/fluxomagnetico_modelofabricado_axis_label.pdf,width=3.34in}}
\centering
\caption{Final model of total flux density inside the electric generator}
\label{fig:densidade_fluxo_maquina}
\end{figure}
use \includegraphics instead:
\begin{figure}%
\centering
\includegraphics[width=1\columnwidth,bb=0 0 394 334]{img/fluxomagnetico_modelofabricado_axis_label.pdf}
\caption{Final model of total flux density inside the electric generator}
\label{fig:densidade_fluxo_maquina}
\end{figure}
The Inkscape generated files must be converted to PDF first and then included using \includegraphics as well. For each file create driver TeX file in this form (bencada.tex):
\documentclass[preview,margin=5pt]{standalone}
\usepackage{graphicx,xcolor}
\begin{document}
\input{img/bancada_geracao.pdf_tex}
\end{document}
compile the driver files to pdf and include them in the main document:
% \input{img/bancada_geracao.pdf_tex}
\includegraphics{bencada.pdf}
You need now configure tex4ht to support PDF images. It can be done using a config file, mycfg.cfg for example:
\Preamble{xhtml}
\makeatletter
\Configure{graphics*}
{pdf}
{\Needs{"convert \csname Gin@base\endcsname.pdf
\csname Gin@base\endcsname.png"}%
\expandafter\getImgFile\expandafter{\Gin@base}{.png}
\Picture[IMG]{\imgBase.png \ifx\noBoundingBox\UnDefined
svg:width="\the\Gin@req@width"
svg:height="\the\Gin@req@height"
\fi
}
\special{t4ht+@File: \csname Gin@base\endcsname.png}
}
\makeatother
\begin{document}
\EndPreamble
you can compile your document now using
mk4ht oolatex Example mycfg
command. You may need to run it twice for the first time, because pdf files are converted in the first run and they will be used only in the consecutive runs.

html2latexconverts from HTLM to LaTeX, but the rest of the post suggests you're doing something else. Then you mention tracking changes which is something Word does, I believe, and Word. But how is this related to the rest? It isn't clear what the files exported by Inkscape are - you don't give an example, which would help people to understand. But Inkscape certainly can export SVG. – cfr Mar 31 '16 at 2:07
