Bridge rectifiers - referred to as BR108-BP - are diodes that are connected in a four-diode bridge configuration. They are commonly used to convert Alternating Current (AC) to Direct Current (DC) in power supplies and other electronics applications. The bridge rectifier is essentially like a full-wave rectifier with the exception that it uses four diodes to achieve the same result.

Working Principle: When an a.c. voltage is applied across the terminals of the bridge rectifier, the diodes D1, D2, D3 and D4 will be alternately in forward and reversed biased conditions. During the positive half-cycle of a.c. supply, diodes D1 and D4 are forward biased and D2, D3 are reversed biased. The current flows through D1 to D4 and returns through D2 and D3, the lowervalued resistance path, as shown in the figure. During the negative half-cycle, the terminals C and D are positive with respect to terminals A and B. Then, the diodes D1 and D2 are reversed biased while diodes D3 and D4 are forward biased, allowing the current to flow from C to A and return through B and D. Hence, during both the half-cycles, the current flows in the same direction and thus a.c. is rectified and smoothened to direct current (dc).

Applications: BR108-BP bridge rectifiers are often utilized in the design of power supplies. They are capable of handling larger currents than the traditional half-wave rectifiers, thus enabling higher power supplies. As such, they are found in almost all power supplies, from consumer electronics to industrial applications where a reliable power source is needed. They are also found in other electronics applications, such as motor drives and control systems where high currents are required.

In addition to power supplies and other electronics applications, BR108-BP bridge rectifiers are being used to develop medical devices and implantable technologies. Implanted devices that rely on direct current are especially suited to these types of rectifiers, as they are an excellent way to convert AC to DC and provide an efficient, reliable source of power.

BR108-BP bridge rectifiers are also found in a wide range of automotive applications. They are commonly used in electric vehicles, hybrid vehicles, and chargers for lead-acid batteries, as well as automotive charging systems, engine control systems, and other types of vehicle electronics. These rectifiers provide a more efficient and reliable power source than traditional power converters, and can be designed to meet the demands of modern automotive applications.

Conclusion: Bridge rectifiers, such as the BR108-BP, are an essential component in many power supplies and other electronics applications. They are capable of handling higher current levels than traditional half-wave rectifiers, and they provide an efficient and reliable source of power, making them ideal for medical devices, implantable technologies, automotive applications, and much more. With their wide range of applications, the BR108-BP bridge rectifier is an ideal choice for any project that requires reliable and efficient power.
