Diodes are essential components when constructing non-linear circuits. Bridge Rectifiers are especially useful due to the way they can convert AC current to DC current with two or four alternate connection methods. BR104 is one of the most widely used models of Bridge Rectifier, famously known for its efficiency, stability, low cost and reliability. In this paper, we are going to take a closer look at what makes this device so versatile and useful.

Applications: BR104 has a wide range of applications, mainly as replacements for transformers and as a general-purpose rectifier. It is mainly used in power supplies and motor control circuits, and is often used in the automotive industry due to its smaller size and lower cost. BR104 can also be used in many other applications, including AC to DC conversion, voltage regulation, voltage multiplier circuits, battery chargers, and more.

Working principle: BR104 is a four-terminal bridge rectifier device that uses two pairs of opposite polarity diodes that are connected in series. The two pairs of diodes are connected in opposite directions in a symmetrical fashion, with two diodes connected in series to form two half-wave rectifier circuits. When AC voltage is applied to the input of the rectifier, it produces a DC output voltage that is a combination of the two half-wave output voltages.

The BR104 has two configurations, the four-diode bridge rectifier, and the two-diode bridge rectifier. The four-diode bridge rectifier is usually a bridge composed of four identical diodes, with an output of full-wave rectification. It is used for applications that require full-wave rectification at a higher voltage than the two-diode bridge rectifier can provide. The two-diode bridge rectifier is a rectifier composed of two identical diodes. It produces a half-wave output, which is sufficient for many low-voltage applications.

When AC voltage is applied to the input terminals, the forward bias of the diodes forces current to flow through the forward biased diode, creating the rectified voltage output. If a bridge rectifier circuit is arranged correctly, current will always flow through one diode in the rectifier circuit, regardless of the input voltage polarity.This allows for full-wave rectification of AC currents.

Advantages: BR104 is one of the most efficient Bridge Rectifiers available on the market, providing up to 95% efficiency when operated at full power. This allows for devices and circuits to be more efficient and can help minimize energy consumption. Additionally, the device has a low voltage drop when compared to other rectifiers, reducing the amount of power that is wasted in the rectification process.

BR104 also has a very low thermal resistance and can handle high-frequency AC currents with very little noise. This makes it an ideal device for use in modern electronic circuits, as it can handle high-frequency signals with very little distortion. Additionally, the device can handle large amounts of current, and is stable when used in higher voltage environments, making it highly reliable.

Disadvantages: Although BR104 is highly reliable, it is not suitable for use in applications where high power levels are required. Additionally, due to the design of the device, it has a limited surge current handling capability, meaning that it is not suitable for applications that require large amounts of current for a short period of time. Additionally, the device has a relatively high reverse leakage current, meaning that it may not be suitable for low-power applications where power is switched on for a short period of time.

In conclusion, BR104 is a highly efficient, reliable, and versatile Bridge Rectifier device. Its low cost and small size make it ideal for a wide range of applications, and its high efficiency makes it a great choice for low-power applications. Additionally, the device has a low voltage drop and can handle high frequency AC currents with very little noise, making it ideal for modern electronic circuits. However, the device has some limitations, such as a limited surge current handling capability and a relatively high reverse leakage current, meaning that it is not suitable for some applications.
