Diodes are an essential type of component found in virtually all electronics applications, from power electronics and automotive applications, to general purpose AC-DC converters. The most widely used type of diode is the single phase rectifier. It is widely used as either a power rectifier, a voltage limiter, or a protection device.

Types of Single-Phase Rectifiers

Single-phase rectifiers are available in two different types, galvanic or electronic. Galvanic rectifiers are implemented using a bridge rectifier circuit. They are suitable for both low power and heavier AC loads, such as those found in larger motors or industrial equipment. Electronic rectifiers rely on a device to control the flow of current, and are typically faster and more efficient than galvanic rectifiers. Commonly used electronic rectifiers are the SCR (silicon-controlled rectifier) and the MOSFET (metal-oxide-semiconductor field-effect transistor).

FFB20UP20STM Application Field and Working Principle

The FFB20UP20STM is a single technical device designed to rectify AC waves into DC waves. The device consists of four junction diodes, allowing current to flow in one direction but not in the other. In most applications, the FFB20UP20STM is used to convert the AC output from an AC power source into the DC output required for a specific application. The diode bridges are effective for applications requiring high voltage, whether the input is a pure DC or pulsating DC. Alternating current set at a frequency of between 50Hz and 400 Hz is applied to the input terminals of the rectifier, thereby producing a direct current equivalent on the output side.

The FFB20UP20STM provides a higher degree of power conversion efficiency compared to other bridge rectifiers. It is rated for an output of 400V and an output current of 40A. Furthermore, it is designed to operate over a wide range of temperatures, from -30°C to + 85°C. The device is also designed with built-in voltage and current limiting, allowing it to safely operate with a wide range of AC input voltages.

The FFB20UP20STM is an excellent solution for a variety of applications, such as wall transformers, backlit LCD displays, HIFI equipment, CD/DVD players, lighting, induction cookers, and other electronics equipment that require DC power.
