NSB8BTHE3/45

Diodes - Rectifiers - Single

Diodes and rectifiers are some of the most versatile components in a wide range of power systems. Rectifiers are used in power supplies and are capable of converting alternating current (AC) to direct current (DC). The NSB8BTHE3/45 is a single phase rectifier module that is well suited for a variety of AC/DC applications.

To understand the working principle of the NSB8BTHE3/45, it is important to have an understanding of the types of diodes which it contains. The NSB8BTHE3/45 comprises of three Schottky Barrier Diodes (SBD), mounted onto a single common heat sink. The three SBDs are arranged in a configuration that bridging two AC inputs and forming one DC output.

Working Principle of the NSB8BTHE3/45

When AC voltage is applied to the NSB8BTHE3/45, the two SBDs connected in parallel act as a full-wave rectifier. This results in the conversion of AC voltage to DC voltage at the DC output. During the positive half of the AC waveform, the top SBD will conduct and output a positive DC voltage which is slightly lower than the incoming AC voltage. During the negative half of the AC waveform, the bottom SBD will conduct and output a negative DC voltage which is slightly lower than the incoming AC voltage. The third SBD, which is connected in series in the circuit of the rectifier, acts as a clamping diode. As the average DC voltage output increases, the clamping diode will regulate the output current. This prevents high inrush currents and voltage exceeding the maximum output level of the rectifier.

Applications of NSB8BTHE3/45

The NSB8BTHE3/45 is well suited for use in power supplies, rectification, DC-DC converters, motor drives and related applications. In power supplies and other applications, it can effectively convert AC input to a regulated DC output with good efficiency. Due to its small size, the NSB8BTHE3/45 can easily be incorporated into small and compact systems. It is also suitable for harsh and industrial environments due to its robust structure and ability to tolerate high surges, transients and EMI (electromagnetic interference) noise.

Conclusion

The NSB8BTHE3/45 is a single phase rectifier module that is ideal for applications where AC is converted to DC. Its three SBDs are arranged in a special configuration that combines two AC inputs and forms one DC output. It is highly efficient, small in size and has a robust construction that makes it suitable for use in a variety of power systems and harsh industrial environments.
