Introduction to DC/DC Converters

DC/DC converters are electrical devices which provide reliable power and voltage conversion between DC different sources. In particular, they are used for renewable energy applications, such as solar and wind energy, as well as in automotive, transportation, medical, and consumer electronics applications.This article examines the VI-B5T-IY-S application field and working principle. VI-B5T-IY-S is a zero voltage switching (ZVS) DC/DC converter from VISEN, an industry-leading supplier of high-performance power supplies. The VI-B5T-IY-S is designed for applications which require high conversion efficiency and high active power capability.

VI-B5T-IY-S Application Field

The VI-B5T-IY-S is suitable for a variety of applications which require high technical performance. These applications include:- Solar and wind energy systems;- Automotive applications;- LED lighting systems;- Medical systems;- Telecommunications;- Data centers;- Uninterruptible power systems;- Elevator systems;- Security and surveillance systems.

VI-B5T-IY-S Working Principle

The VI-B5T-IY-S is a ZVS DC/DC converter. This means that it is designed to reduce power losses in the power transfer stage. This is made possible by the ZVS technique, which enables the input voltage to be equalised to that of the output voltage at switch-on. As a result, power losses due to voltage differences are minimised within the power transfer stage.The VI-B5T-IY-S achieves this by using an active rectifier stage which is operated in quasi-resonant (QR) mode. The rectifier’s active stage determines the operating frequency, the duration of which is determined by the input voltage. It is on this basis that the input source and the output load are synchronised to deliver power with the highest conversion efficiency.

VI-B5T-IY-S Operation Parameters

The VI-B5T-IY-S ranges from 0 to 275V, with an average efficiency of 98-99%. Its output power is adjustable from 0 to 300W, with a maximum output current of 10A. It also features an active frequency jittering function which helps to reduce EMI emissions.

Conclusion

In conclusion, the VI-B5T-IY-S is a high-performance ZVS DC/DC converter designed for a range of applications which require high technical performance. It is an energy-efficient device which helps to reduce losses in the power transfer stage, enabling it to deliver the highest conversion efficiency. Furthermore, it offers a range of adjustable features – such as active frequency jittering and the ability to adjust the output power – which makes it suitable for a wide variety of different applications.
