DC DC Converters:VI-BNT-CV-F4 Application Field and Working Principle

DC-DC converters are devices used for converting direct current from one voltage level to another. Reversible DC-DC converters are capable of either increasing or decreasing the input voltage. The VI-BNT-CV-F4 is a reversible DC-DC converter from TDK Corporation. It provides a wide range of input from 24 to 60 VDC and output of 6 to 15 VDC at up to 4 A. This converter is suitable for a variety of applications such as telecom, networking, computers and industrial control.

Application Field

VI-BNT-CV-F4 is mainly used for powering up Point-of-Sale (POS) systems, Electronic Cash Registers (ECR), Cell Phones, Networking products and Industrial Control applications. This particular model is used for applications where input voltage is highly adjustable and is located in environments that require high isolation and interference reduction. With the adjustable input voltage, the converter can operate on input voltage levels from 24 to 60 VDC and ensure it has proper output voltage of 6 to 15 VDC.

VI-BNT-CV-F4 also offers a high efficiency for better power quality. Furthermore, it supports a wide temperature range operation from -40°C to +85°C. This wide temperature range makes it suitable for many different environments. Its compact design fits for space-constraint applications.

Working Principle

The workings of VI-BNT-CV-F4 is done through the use of a switching bridge circuit. This consists of semiconductor transistors connected in series and parallel. When power is supplied to the circuit, the transistors conduct and switch, thus controlling the input current to the output voltage. As the transistors switch, they create ripples in the output voltage and therefore lead to an increase and decrease in the output voltage. The switching bridge is very efficient and can be used in many different applications such as power supplies and motor speed control.

To regulate the output voltage, there is an internal voltage reference. This voltage reference will cause the bridge to switch faster or slower depending on the output voltage set-point. This, in turn, creates a smooth output voltage. The internal voltage reference also allows for precise control of the output voltage.

Conclusion

The VI-BNT-CV-F4 is a reversible DC-DC converter that is useful for a variety of applications. Its adjustable input voltage, high efficiency, wide temperature range and compact design make it suitable for different environments. Working of VI-BNT-CV-F4 is done through the use of a switching bridge circuit and an internal voltage reference. This allows for precise control of the output voltage.
