Diodes are essential semiconductor components used in many circuits. One of the most popular types of diode is the bridge rectifier. They are widely used in DC power supplies, such as VBO88-18NO7, to convert an AC voltage into a DC voltage. In this article, we\'ll look at its application field and working principle.

The VBO88-18NO7 bridge rectifier is a four-terminal device containing four diodes configured in a bridge formation. It is commonly used to convert AC voltages from a line-voltage source (mains) into DC voltages. Its terminals are labeled with the symbols shown in the picture below.

The application field of the VBO88-18NO7 bridge rectifier includes AC-to-DC power conversions, AC power supplies, Battery Chargers, DC-DC Converters and more. It is also frequently used in automotive, lighting, and power management applications.

The working principle of the VBO88-18NO7 bridge rectifier is quite simple. When alternating current (AC) from the line-voltage source is applied across terminals A and B, as shown in the picture above, the diodes D1 and D4 become forward-biased, allowing current to flow from terminal A to B. At the same time, the diodes D2 and D3 are reverse-biased, preventing current from flowing from terminal B to A. This creates a half-wave rectifying effect, and the result is a pulsating DC voltage at terminals C and D.

When the line-voltage reverses its polarity, as it typically does at regular intervals, the diodes D1 and D4 become reverse-biased, and the diodes D2 and D3 become forward-biased. This allows current to flow from terminal B to A and prevents current from flowing from A to B, resulting in an opposing half-wave rectification effect. This alternating and alternating-opposing effect results in pulsating DC voltage at the output.

The VBO88-18NO7 bridge rectifier provides several benefits. It is capable of converting an AC voltage into DC with a minimum of components, thus allowing for a circuit with a small physical footprint. It also provides full wave rectification, allowing for better efficiency and faster current responses than with a single-phase rectifier. Additionally, it provides a high level of current handling capacity and reverse voltage protection, making it an excellent choice for many applications.

In conclusion, the VBO88-18NO7 bridge rectifier is a highly versatile, cost-effective diode device designed for wide range of AC-to-DC conversion applications. Its user friendly design, robustness, and attractive price make it a great choice for projects requiring full-wave rectification.
