DC DC Converters provide an efficient method for transforming electricity from one voltage or current level to another. The VI-21Y-MU, released by the Danish company Vicor, is one such converter that is widely used in contemporary electronics and electrical engineering applications. This article will discuss the field of applications and the working principle of this DC to DC converter.

Fields of Application

The VI-21Y-MU is an advanced DC to DC converter, designed for use in high-end applications. It supports a wide voltage input range of 8-76V and delivers a reliable output of 21W (at an output voltage of 20V). This makes it suitable for powering embedded processors, FPGAs and other high performance server applications. Additionally, the VI-21Y-MU has a high frequency switching capability, which allows it to be used as a regular power supply in a wide range of consumer electronic devices such as telecoms, base stations, and computers.

Additionally, the VI-21Y-MU also contains several built-in protection features, such as over-current, over-voltage and thermal protection, providing reliable performance in hazardous environments. This has led to it being used in medical and industrial applications, such as medical imaging equipment and factory automation systems.

Working Principle

The VI-21Y-MU converts DC voltage to a desired AC output voltage or current level by employing an inverse current control technique. This technique suppresses current spikes in the converter, preventing voltage dips and other instabilities, while also conserving power. This ensures a constant voltage and current output from the converter, even under varying load conditions.

The VI-21Y-MU also includes a dynamic voltage feedback loop which keeps the output voltage stable, regardless of sudden changes in the input voltage or load. This is achieved by automatically adjusting the switching cycles of the converter, based on the input and output voltages. This makes the converter ideal for applications that require precise and consistent output voltages.

Overall, the VI-21Y-MU is an effective DC to DC converter, capable of delivering reliable power in a variety of applications. Its high frequency switching and built-in protection features make it an ideal choice for powering embedded processors, FPGAs, and other electronic devices in a wide range of scenarios.
