BR68

A bridge rectifier, sometimes known as a full-wave or a double-wave rectifier, is a type of diode circuit used to transform AC input into DC output. It is generally used to convert AC power in multiple examples such as power supplies, UPSs, inverters, and chargers. This article will discuss the applications and functions of the Bridge Rectifier BR68, as well as its structural and theoretical operating principles.

The BR68 is a four-terminal bridge rectifier comprised of four diodes; two in the lower flow loop and two in the upper loop. In operation, these four diodes are connected together in series, allowing for DC output from the alternating current (AC) input values. Since bridge rectifiers require twice the current of a half-wave rectifier to obtain the same output, the BR68 can be used for applications that require a higher current rating. One such example is in welding machines, where high currents are required for continuous operation.

The BR68 can also be used in applications such as automotive and emergency lighting, police vehicles, serial backlights, LED driver power supplies, consumer electronics and other consumer appliances, and even in building automation systems. Its high efficiency and low peak reverse voltage make it well suitable for these applications. In addition, its low ripple factor makes it ideal for lighting applications, as the BR68 output give a consistent brightness and color regardless of the input AC signals.

The working principle of the BR68 is simple but effective. As discussed previously, the BR68 is composed of four diodes: two in a lower flow loop, and two in an upper loop. When AC input is supplied to the BR68, the four diodes allow for current flow through the lower and upper loops, creating a full-wave rectification circuit and ultimately providing a regulated DC output. This rectification process effectively transforms AC input into DC output.

The BR68 also has several safety features. Its low reverse peak voltage makes it more suitable for a range of electronic devices and its built-in fuse helps protect against any potential damage from overcurrents. Its small size and light weight also contribute to its convenience and application flexibility, making the BR68 an optimal option for a variety of design applications.

In summary, the BR68 is a four-terminal bridge rectifier utilized in various applications such as power supplies, UPSs, inverters, chargers, LED lighting systems, and consumer electronics, to name a few. Its working principle is based on the connection of four diodes, providing a full-wave transformational circuit and DC output. The rectification process allows for AC input to be converted into a safe and regulated DC output. Its low reverse peak voltage, high efficiency, and low ripple factor make it a highly desirable choice for a wide range of applications.
