Designing specific DC power supply from AC source:

A power supply converting AC line voltage to DC power must perform the following functions at high efficiency and at low cost. The advantage of this kind of power supply over batteries is that this power supply is low cost and also long lasting. We have to perform the following functions to convert AC power to DC power:

    • Voltage transformation
    • ¬†Rectification
    • Filtering
    • Regulation
