ABSTRACT
Most electronic equipment and circuits require DC sources for their operation. Dry cells and rechargeable batteries can be used for these applications but they only offer limited power and unstable voltage. The most useful DC sources are AC/DC converters. The technology of AC/DC conversion is a wide subject area covering research investigation and industrial applications. AC/DC converters (usually called rectifiers) convert an AC power supply source voltage to a DC voltage load. Uncontrolled AC/DC converters usually consist of diode circuits.
