Introduction

Diodes are perhaps one of the most ubiquitous components found in almost any electrical circuit. They are widely used in the majority of consumer electronics, automotive systems and industrial applications. One type of diode, referred to as a bridge rectifier, plays an important role in providing efficient conversion of alternating current (AC) to direct current (DC). This article will discuss the application field and working principle of the ABS20M RGG bridge rectifier.

ABS20M RGG Bridge Rectifier

The ABS20M RGG bridge rectifier is one of the more popular designs of bridge rectifiers as it is both cost-effective and reliable. This four-terminal, dual-output bridge rectifier is capable of converting AC voltage into DC voltage with a maximum current of 20A and a maximum peak reverse voltage (VRRM) of 400V. It has a dual center-tapped output, allowing the output voltage to be split into two separate voltages. It also features low leakage current, a low temperature coefficient, and a relatively low forward voltage drop.The ABS20M RGG bridge rectifier is designed to operate in both a single-phase and three-phase AC power systems. In a single-phase system, only the two AC mains voltage lines are used to input power and only one of the two outputs is used, while in a three-phase system, three AC mains voltage lines are used and two of the outputs are used. This rectifier also includes two freewheeling diodes with a maximum continuous forward current rating of 2A and a maximum reverse voltage of 400V. These diodes provide protection for the bridge rectifier and other downstream components from voltage spikes and other forms of overvoltage.

Working Principle

The basic idea behind a bridge rectifier is to convert an AC waveform into a DC waveform. To accomplish this, the bridge rectifier utilizes a bridge circuit composed of four diodes arranged in a specific configuration. The four diodes block the negative half of the AC waveform, while allowing the positive half to pass through, resulting in a DC signal.When an AC voltage is applied to the bridge rectifier, it is split into two components: one travelling through diode 1 and diode 4 and the other through diode 2 and diode 3. These components then recombine to form a unidirectional current which is transmitted to the output terminals. The two freewheeling diodes in the ABS20M RGG bridge rectifier provide protection for the bridge by conducting current around the bridge during moments of overvoltage, preventing damage to the bridge circuit.

Conclusion

The ABS20M RGG bridge rectifier is a popular bridge rectifier that is commonly used in both single-phase and three-phase AC power systems. It has a maximum current of 20A and a 400V maximum peak reverse voltage rating. The two freewheeling diodes provide protection for the bridge circuit and downstream components from overvoltage. Its simple configuration and reliable performance have made it a popular choice among commercial and industrial users.
