Single-phase bridge rectifiers are widely used in AC/DC power conversion systems, and MBR3100G is an ideal choice for applications where high power and efficiency is of importance. By combining three (one) forward and three (one) reverse diodes, MBR3100G dual-stage rectification converts the AC input voltage to DC output. This rectification process eliminates the traditional large-capacity filter capacitor, resulting in the reduction of costs, volumetric size and the output ripple and noise significantly.

The application fields of MBR3100G span from power supplies to industrial equipment. It is especially advantageous in applications that have a floating AC input. The MBR3100G enables conversion of a three-phase (or single-phase) AC input to a DC output at the same voltage level, providing full galvanic isolation between the input and the output. On industrial level, MBR3100G can be employed in lighting control, uninterruptible power supplies, inverters, solar power systems, LED drivers, UPS, power plants, telecommunication systems, battery chargers and other AC-DC power converters.

In the working principle of MBR3100G, the three (one) internally connected diodes form a shunt for the reverse current through the return capacitance of the power system and the forward diodes provide the break. When the AC power crosses the zero-voltage point, the forward diodes in the bridge pass current to the load, allowing DC power to flow from the negative terminal to the positive terminal. Then, the reverse current returns to the input capacitance of the power system.

In a single-phase bridge rectifier, the current flow is unidirectional and fixed. This makes it a very stable, reliable and cheap power supply source. The main advantages of using MBR3100G are low cost and efficient power conversion with high power handling capability. Moreover, it is also easy to install and maintain. The built-in thermal protection circuit also prevents any possible damage to the rectifier by keeping it away from over-heating.

Apart from the basic features mentioned above, MBR3100G also provides additional features such as dynamic surge absorbance capability and voltage transients protection. Combining these features makes it suitable for harsh electronic environments and demanding applications. Additionally, its bidirectional design allows it to be used in a floating input system.

Since its introduction, MBR3100G has been found to be an ideal device for various applications that have stringent requirements regarding power quality, energy efficiency, and reliability. Thanks to its robust design, it can withstand extreme conditions and is certified to long-term operation with a high level of consistency. Additionally, its excellent surge voltage withstand capability makes it an ideal choice for applications with high transient voltages.

To sum up, the high-power and efficient MBR3100G dual-stage rectifiers have various advantages compared to traditional rectifiers. It is a low-cost solution for applications with AC/DC power conversion needs, providing stable and reliable power supply with low output ripple and noise. Thanks to its bidirectional design, it is suitable for applications that requires high voltage transients protection and dynamic surge absorbance.
