Introduction

A Half-bridge-series-to-junction-anode Rectifier (HS2JA R3G) is a commonly used rectifier module of three-phase power supply systems. It is used for rectifying AC power in the field of power supplies. It is composed of two diodes and a junction-anode rectifying unit, and is often referred to as a “3-pin, 2x2x1-diode bridge rectifier”.

Construction and Operation

The HS2JA R3G essentially consists of two separate diodes and a junction-anode rectifier in a single compact housing. This rectifier has an integrated reverse-polarity protection and requires a minimum of inrush current at start-up.The circuit of the device is essentially a bridge rectifier with two diodes connected in series. During normal operation, the diode connecting the bridge rectifier’s output to the junction-anode rectifier’s anode edge is forward-biased, thus allowing current to flow from the input to the rectifier’s output. The second diode connecting the junction-anode rectifier’s cathode edge to the input is then reverse-biased, thus blocking current from flowing back to the input.This type of rectifier module is designed for a broad range of applications, including single phase bridge rectifier applications, three-phase rectifier applications, single phase boosted bridge rectifier applications, and reverse linear regulator applications.

Applications of HS2JA R3G

HS2JA R3G is useful in applications such as power supplies and generated power saving. With its reverse-polarity protection and low power consumption, it is suitable for use in a variety of power supplies, including LED lighting, LED lighting controllers. It can also be used in DC motor control, power factor correction and power line communications applications.HS2JA R3G modules can also be used in automotive electronics, such as battery powered electronic devices. They provide an efficient power solution for safe running of automotive devices that require low-current levels. Moreover, these modules are also used in various military applications, such as electro-optical systems and in communication sites.

Working Principle of HS2JA R3G

The HS2JA R3G rectifier works in a manner similar to a conventional single phase half-wave rectifier; however, with the addition of the junction-anode rectifier, the circuit can be designed to generate a higher output current. The advantage of this circuit lies in its ability to provide up to twice the current outputs of a conventional single phase bridge rectifier, while still maintaining a low voltage drop across the diode components.At the same time, the increased voltage output of the junction-anode rectifier prevents current reversals, resulting in improved power factor performance. This also means that the HS2JA R3G can be used in applications where power factor correction is needed, making it ideal for high-power applications. The HS2JA R3G rectifier module is capable of working with both AC and DC power supplies. When using AC power, the rectifier’s internal circuitry will regulate theinput voltage to a required direct current level and then provide the output voltage. This is achieved through the use of the junction-anode rectifier, which allows for more efficient power transfer than is possible with conventional single phase bridge rectifiers.When using DC power, such as a battery, the HS2JA R3G module is able to provide higher output current than is possible with a conventional bridge rectifier due to its ability to sense the level of voltage required and then regulate the output accordingly.

Conclusion

The Half-bridge-series-to-junction-anode Rectifier module is a versatile, efficient, and reliable solution for rectifying AC and DC power, particularly in applications such as power supplies and generated power saving. Its added benefit of reverse-polarity protection and low voltage drop also make it an ideal choice for applications where higher current outputs are required. Furthermore, the HS2JA R3G is able to work with both AC and DC power supplies, making it a convenient and effective rectifying solution for virtually any application.
