Today we are going to talk about the application field and working principle of Vs-26MB05A. This device is belong into the Diodes – Bridge Rectifiers. Also because of its light weight and compact nature, these devices often used for a variety of applications including DC to DC converter, AC to DC rectifier, voltage doubler, and even in power factor correction circuits.

Bridge rectifiers are full wave rectifiers meaning they switch polarity of the voltage across the load every half cycle of the AC input of the input voltage. The Vs-26MB05A rectifier consists of four diodes configured in a bridge circuit. It converts alternating current (AC) to direct current (DC) and comprises two input terminals and two output terminals.

To better understand its working principle, let us consider the schematic of Vs-26MB05A:

As shown in the above schematic diagram, the Vs-26MB05A bridge rectifier is made up of four diodes connected in a closed circuit known as the “bridge”. Two input terminals are connected across the two supply lines (either the live and the neutral line of an AC supply circuit, or the positive and negative line of a DC supply circuit) and two output terminals are connected across the load. The positive line of the AC supply is connected to the upper left node of the bridge while the negative line is connected to the upper right node.

For each half cycle of the AC supply an unequal but opposite potential is applied across the two terminals, due to which a forward-biased p-n junction is formed in a diode. This massive current flow through the diode and allows the electrical current to flow in one direction only. The other three diodes follow the same functioning. During the positive half cycle of the AC supply voltage, diodes D1 and D3 get forward biased and the load current flows through D1, load, and D3, reversing its direction for the next negative half cycle since this time D2 and D4 get forward biased.

When compared with other full wave rectifiers, the Vs-26MB05A has the advantage of conducting more than twice as much as current through the load than a normal single phase full wave rectifier, because two diodes conduct simultaneously during each half cycle. The Vs-26MB05A bridge rectifier also has a much lower forward voltage drop across the terminals than a conventional rectifier.

Considering the overall, the application fields of the Vs-26MB05A bridge rectifier are quite vast due to its reliable functioning and low power losses. It is mainly used for rectification of AC power in DC to DC converters, AC to DC rectifiers, battery charging, inverters, power factor correction circuits, power supplies, UPS, battery chargers and other electronic circuits.

Voltage regulation is another application of the Vs-26MB05A rectifier. It can efficiently maintain the load voltage with varying load current by regulating the input voltage. It also helps with other applications such as lighting, input power conditioning, voltage stabilization, etc. It also acts as an over-voltage protector, protecting sensitive electronic devices from sudden power surges.

These above mentioned points are enough to provide an idea about the Vs-26MB05A bridge rectifier, its application fields and working principle. However, for more details about the same, it is recommended to read the device datasheet.
