Diodes - Bridge Rectifiers LBS10-13 Application Field And Working Principle

Bridge rectifiers are a type of rectifier which uses four or more diodes to convert an alternating current (AC) input into a direct current (DC) output. Thus it is named a bridge rectifier as the diodes form a bridge between the input and the output. Typically the bridge rectifier is used in electronics to convert an AC voltage from a transformer to a DC voltage. The bridge rectifier diodes are designed for higher current ratings for this purpose.

Application Field

Bridge rectifiers are commonly used in AC-DC power supplies which are found in a variety of electrical appliances such as televisions and computers. This type of rectifier is also used for applications such as motor control and power converters, battery chargers, and reverse-voltage protection. The bridge rectifier is preferred over other rectifiers such as the half-wave rectifier because it produces a higher voltage output compared to the half-wave rectifier and has the capability of handling higher current loads.

LBS10-13 Series

The LBS10-13 Series of bridge rectifiers is a high power density and high current rating rectifier module which is suitable for applications in both AC and DC power supplies between 10A and 13A. Typical features of the series include a load current of 10A to 13A, a low contact resistance of 0.01 ohms and a low operating temperature of 55°C. The series also offers a compact size, making it ideal for use in small, confined spaces. The series is available in through-hole, SMD and DIP package configurations so it can be conveniently used in a variety of applications.

Working Principle

A bridge rectifier works by using an alternating current which is sent through four individual diodes arranged in a bridge configuration . The diodes are responsible for ensuring that the current flows in one direction only, by converting the alternating current current into a DC current.This process is driven by the need to use a less expensive transformer with two windings, that not only reduces the size of the transformer but also the cost of the rectifier.

The diodes are arranged in a bridge formation so that the input is divided into two parts, each part receiving half of the total voltage. This ensures that one of the two branches receives the positive half-cycle of the input voltage, while the other receives the negative half-cycle. During the positive half-cycle, the upper branch of the diode bridge is forward biased, while the lower branch is reversed biased. During the negative half-cycle, the situation is reversed and the lower branch is forward biased.

The end result is that the output voltage is always positive with respect to the negative output terminal. This allows for the creation of a DC current from an AC input. The advantage of this type of rectifier is that it ensures the output voltage is always positive even when the input voltage is negative, and thus offers more efficient power conversion.

Conclusion

The LBS10-13 Series of bridge rectifiers is a great choice for both AC and DC power supplies due to its compact size, high power density and high current rating. The bridge rectifier is also an ideal choice for applications where a high output voltage is required, due to its capability of converting AC voltage to DC current. The working principle of the bridge rectifier works by using four diodes arranged in a bridge configuration, which divides the input current into two parts and ensures that one branch receives the positive half-cycle of the voltage, while the other receives the negative half-cycle, resulting in a positive DC output.
