  • What is Rectifier? - Know its uses and applications

    Applications and Uses of Rectifiers. The primary application of the rectifier is to derive DC power from AC power. Rectifiers are used inside the power supplies of almost all electronic equipment. In power supplies, the rectifier is normally placed in series following the transformer, a smoothing filter, and possibly a voltage regulator.

    The main difference is the number of turns a winding has on the primary coil vs the secondary coil. More turns on the primary coil will give you a step-down transformer which reduces the voltage from the input to output whereas a step-up transformer would be constructed the opposite way; more winding turns on the secondary for increased voltage.
