DC DC Converters

DC DC converters are electrically powered devices that convert a direct current (DC) input into a different DC output. These devices are essential in a variety of applications, including computer power supplies, automotive electronics, and portable electronic devices. The VE-21T-MW is a high-power DC-DC converter made by Murata. It has a wide range of applications, thanks to its adjustable output voltage and current rating. In this article, we will discuss the application field and working principle of the VE-21T-MW.

Application Field

The VE-21T-MW is primarily designed for use in electric vehicles. It is a high power-density device that can easily fit in the limited space available in the battery pack of electric vehicles. The VE-21T-MW is also suitable for use in other harsh environments, such as industrial processes, where reliable power delivery is required. In addition, the VE-21T-MW is suited for use in medical and military equipment due to its high efficiency, reliability, and long lifespan.

Working Principle

The VE-21T-MW is a full-bridge Rectifier-Type DC-DC converter, meaning that it is capable of converting both positive and negative input voltages into a single positive output voltage. The input voltage is connected to a full-bridge rectifier, which converts the AC input voltage to a rectified DC voltage. This rectified DC voltage is then fed into an inductor, where it is stored in an electromagnetic field. This stored energy is then released in the form of current through the inductor to the output. The output voltage is adjusted according to the user\'s needs by varying the ratio of the inductor\'s turns.

The VE-21T-MW is capable of delivering up to 700W of power with a power density of 6.8W/cm³. The device is also equipped with a short circuit and over-temperature protection circuit, which prevent the unit from being damaged if it is exposed to extreme conditions. In addition, the VE-21T-MW is RoHS and CE-compliant, indicating that it is safe for use in commercial and residential environments.

Conclusion

The VE-21T-MW is a high-power DC-DC converter built to withstand harsh environments. It is designed for use in a variety of applications, including electric vehicles, industrial processes, medical equipment, and military equipment. The device features a full-bridge rectifier-type design, adjustable output voltage, and short circuit and over-temperature protection circuits. The VE-21T-MW is RoHS and CE compliant, ensuring that it is safe for use in residential and commercial environments.
