AC to DC Converter Chips

AC to DC converter chips transfer AC input into DC power using either switching or rectification. Conversion by switching involves using electronic components such as metal oxide semiconductor field effect transistors (MOSFET) or insulated gate bipolar transistors (IGBT). Conversion by rectification involves using electronic components that conduct electric current in only one direction, such as a Schottky diode that uses a metal layer to contact the semiconductor element. AC to DC converter chips are known by a variety of names, including AC DC converter chips and AC DC conversion chips. They are also referred to as AC/DC converter chips and AC/DC conversion chips.

AC to DC converter chips are used in many AC/DC conversion devices, including AC/DC adapters, AC/DC converters, and AC/DC power supplies. AC/DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage. Many DC devices use these adapters or power supplies and include household items, printers, and low-voltage DC boards. Some AC to DC converter chips are an integral part of electronic circuit boards.

Rectifier chips or diodes are composed of two-terminal electronic components that allow current to flow in only one direction, from an anode (+) to a cathode (-). A rectifier chip is typically made of semiconductor materials such as germanium, silicon, or selenium. Rectifier chips are configured in several varieties, including bridge, center-tap, Schottky, and fast recovery. There are many AC to DC conversion applications for rectifiers, including variable speed drives, battery chargers, and DC power supplies.

Switching chips for AC to DC converter chips include bipolar- junction transistors (BJTs) and field-effect transistors (FETs). Metal oxide semiconductor field-effect transistors (MOSFETs) are a type of field-effect transistor with a built-in capacitor as the input and a conducting channel as the output. Another type of switching chip is the insulated gate bipolar transistors (IGBT). These AC to DC converter chips are semiconductors that combine a high voltage and high current bipolar junction transistor (BJT) with a low power and fast switching metal-oxide semiconductor field-effect transistor (MOSFET). IGBTs provide faster speeds and better drive and output characteristics than power BJTs and offer higher current densities than equivalent high-powered MOSFETs.
