DC DC converters are electrical components that convert direct current (DC) electricity from one voltage level or intensity to another. The V72B24T250BF3 is an example of a specific type of DC DC converter. This article will explore the application field and working principle of this component.

Application Field of V72B24T250BF3

The V72B24T250BF3 is designed for use in uninterrupted power supply (UPS) systems, providing isolated power conversion from DC power sources ranging from 24-60V to a regulated 12V output. The component has excellent noise suppression using its EMI filters, both at the rectified input and the regulated output, helping to ensure smooth and reliable power conversion. It has a wide operating temperature range, from -40°C to +70°C, and it provides up to 250W of output power.

The V72B24T250BF3 has a robust design that has been tested for 2,500 hours at full load under strict conditions, offering reliable and efficient power for both industrial and professional settings. Its high-efficiency design limits operating costs and will help to lower the cost of ownership in the long term. Additionally, the component comes with a six-year warranty, further reducing any potential financial burden on the user.

Working Principle of V72B24T250BF3

The principle of operation for the V72B24T250BF3 is straightforward but highly efficient. The component utilizes a switching regulator design that is powered by an insulated gate bipolar transistor (IGBT). This technology allows the DC power source to be converted to the required voltage, within a specified current limit, while providing high efficiency, low noise, and high reliability in operation.

The IGBT is controlled by a switchmode power supply (SMPS) controller chip. This chip provides the necessary control for the IGBT to regulate the output voltage and maintain the desired current limit. It also features current limiting protection to protect the component from overload and over temperature conditions.

The V72B24T250BF3 features a built-in active PFC (power factor correction) circuit to maximize efficiency by reducing power loss as well as maintaining a minimum system power factor. This circuit ensures a low total harmonic distortion (THD), as low as 5%.

The component is also equipped with a comprehensive range of protections, including output overcurrent, output short circuit, output over voltage and input under voltage protection. In addition, the V72B24T250BF3 also includes an active-inrush limiting circuit to protect load equipment from the inrush current caused by frequently switching supply loads.

Conclusion

In conclusion, the V72B24T250BF3 is an efficient and reliable DC DC converter designed for use in UPS systems. It is robustly built to withstand extreme temperatures and has been extensively tested to ensure long-term operation. It also features a comprehensive set of protections, including power factor correction and active inrush limiting, to protect both the equipment and the component itself. It is available with a six-year warranty, ensuring an excellent return on investment.
