BAV103,135

Introduction

The BAV103,135 are diodes that form the most basic structure of a rectifier. Rectifiers are widely used for the conversion of AC signals to DC signals. Consisting of a single P-N junction, rectifiers are used to rectify AC currents from an alternating current supply, attenuate high frequency interference or build a bridge between a DC power source and a load. Common applications of rectifiers include power supplies, high-voltage DC stabilizers, and electric instrumentation.

Types of Rectifiers

There are two main types of rectifiers: full-wave (FW) and half-wave (HW).

• Half-wave Rectifier - A half-wave rectifier uses single diodes to convert alternating current to unipolar DC current by cutting off the negative cycle and allowing only the positive cycle to pass through.
• Full-wave Rectifier - A full-wave rectifier converts both the positive and negative cycles of an AC current to DC current by using a bridge configuration. This produces a symmetrical, unipolar output.

BAV103,135 Applications

The BAV103,135 are single-diode half-wave rectifiers. They have many applications, including switching regulators and voltage regulators. These rectifiers are also used in relays, audio vacuum tube circuits, and power factor correction capacitors. Other applications include automotive batter y charging and lighting dimmers.

The BAV103,135 rectifiers also have applications in computer power supplies, energy transformers,and uninterruptible power supply (UPS). In a UPS system, the rectifier converts AC input to DC power, which is then stored and converted to AC output.

BAV103,135 Working Principle

The BAV103,135 rectifiers work on the principle of the P-N junction. When an AC voltage is connected to an N-type semiconductor material, the N material is integrated with electrons and the P-Type material is integrated with holes. The electrons then move toward the P-type area and the holes move towards the N-type area, resulting in the formation of an electric bias.

When current is applied to the P-type side and the N-side is connected to ground, the current flows from the P-type area to the N-type area and passes through the P-N junction. This allows a unidirectional current and blocks the reverse biased current. The BAV103,135 perform this operation by using a single P-N junction and blocking the reverse current.

Conclusion

The BAV103,135 are single-diode rectifiers that convert alternating current to unipolar (DC) current. They are used in a variety of applications, including switching regulators, voltage regulators, relays, audio vacuum tube circuits, power factor correction capacitors, and automotive battery charging. The working principle of the BAV103,135 is based on the P-N junction, allowing a single diode to block the reverse biased current.
