    I need help to construct a bridge rectifier in order to convert 120VAC to 135VDC. Thanks

    What current? People generally use 1N4007 diodes or a bridge package rated at 600v or greater.

    Please be aware that simply rectifying the AC line without using an isolation transformer is extremely dangerous. Simply stated, every part of the circuit constitutes a letha shock hazard, and there is no way to make it safe.

    Do not risk your life or find you have been responsible for harm to otheres because you did not handle electricity safely.

    Better to use an isolation transformer and then rectify the AC.

    To the OP:

    I do not respond to email requests. All dialogs should take place in the forums.

    Trying to place a common ground into a line-rectified circuit will result in fireworks. The AC you work with must be isolated by means of a transformer.
