Diodes have various applications in the power electronics area. A bridge rectifier, namely VS-91MT120KPBF is used in a wide range of applications such as AC to DC power conversion, DC to DC power conversion, and uninterruptable power supply (UPS) etc.

The Working Principle of Bridge Rectifiers

As the name suggests, a bridge rectifier consists of four diodes connected in the shape of a bridge. The diode bridge is also known as a full wave bridge rectifier as it can convert both the positive and negative half cycles of the input AC wave into DC. The figure below shows the diagram of bridge rectifier.

The purpose of the bridge rectifier is to convert the given AC voltage into a DC voltage with no change in the peak value of the AC wave. The bridge rectifier is composed of two sets of diodes arranged as a bridge. When the input AC voltage is given to the diode bridge, two of the diodes in the bridge become forward biased and two diodes become reverse biased. The AC voltage is thus converted into DC voltage using only two of the four diodes of the bridge.

In the case of the VS-91MT120KPBF bridge rectifier, when an alternating current is applied to it, one diode becomes forward biased while the other three become reverse biased. This results in the AC current being converted into DC current with equal peaks in both the positive and negative half cycles. Moreover, the VS-91MT120KPBF can withstand higher voltage and current values than the standard bridge rectifier.

Application Fields of Bridge Rectifiers

Bridge rectifiers have various applications in the power electronics area. They are used in AC to DC power conversion, DC to DC power conversion, and uninterruptable power supply (UPS) etc. The VS-91MT120KPBF bridge rectifier is generally used in applications requiring high voltage and current values, for example it can be used for heavy industrial applications in power electronics.

The VS-91MT120KPBF bridge rectifier also has other applications, such as in AC motor drives, solar energy systems, electric vehicle chargers, and other power electronic systems requiring high voltage and current values.
