    I am suppose to design a full wave rectifier by SCR. But I have no idea what it is, someone helps me to get some ideas.

    I'll bet they are talking about an SCR controlled full-wave rectifier.

    If you are making a high-current regulated power supply with a variable voltage output, it is good practise to have a preregulator ahead of the output regulator. Using the SCR's to keep voltage on the filters about 2 volts above the regulated output means the passers can run close to saturation and avoid ohmic heating.
