    I want to rectify 1-3vac to 1-3vdc. Does anybody know
    which bridge rectifier would give me the lowest possible
    voltage and amperage loss available today. Please help
    this "ole man".

    Many thanks

    Lowest Voltage loss and highest current allowed would be a synchronous rectifier. Essentially, P and N MOSFETs in a bridge that are switched on/off via an external circuit rather than "automatically" via forward voltage drop.

    Using "passive" rectification, Schottky diodes (linked in post above) are the lowest Vf of the choices available. A bridge with Schottky diodes drops about .75V rather than 1.5V.
