'[EE]:Rectify'

Get a transformer that's .707 x that of the current one?  :)  You might try
a regulator after the rectifier; but you haven't given what your
requirements are (current, line regulation requirements, etc.), so it's
difficult to suggest something.  The larger EE oriented sites have quite a
few electronics theory sites that you might want to take a closer look at.

A quick google search turned up these:
http://www.electronicsinfoline.com/circuitbook/Power_Supply/Theory/

http://sfe-dcs.com/Theory/PowerSupplies.html

These should get you started to answering some of the questions you might
have.

I have got problem when I trying to
rectify AC voltage from a transformer
with a rectifier bridge the output voltage
will be 1,41 x higher then the AC output.

Do anyone know any way to rectify the
AC voltage and get the same value
output as DC voltage?

Use a controled rectifier! Two diodes and two thyristors or if three
phase 6 thyristors ! Control the phase angle and you have a variable dc
voltage !( a dimmer for DC)

Here is one way of doing it along those lines:

Now, that's ingenious!  Using the parts of the power cycle
that the other power supplies throw away!  This could
be the solution to the "power factor crisis" supposedly
being caused by all the personal computers and other
electronic devices with switching supplies.

I can buy "power factor corrected" supplies.  You think
they do something like this?
