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 [1]. 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. UncontrolledAC/DC converters usually consist of diode circuits. They can be sorted into the following groups [2]:
• Single-phase half-wave rectifiers • Single-phase full-wave rectifiers • Three-phase rectifiers • Multipulse rectifiers • PFC rectifiers • Pulse-width-modulated boost-type rectifiers.
