I think this is not a question for latex2html but for LaTeX.

If you want the output such as the latter one for the first
source, you may do

$$y=\textstyle\sum_{i=1}^n x_i$$

If you want the output such as the first one for the latter
source, you may do

$$y=\frac{1}{\displaystyle\sum_{i=1}^n x_i}$$
