DC DC Converters

DC DC converters are electronic devices used to convert direct current (DC) to direct current of different values, frequencies, or voltages. In other words, they convert DC electricity from one form to another. A DC DC converter can be used to rectify voltage levels within the same type of system or to step down from higher to lower voltages in different applications. With the development of modern science and technology, converter technology has made great progress and a variety of DC converters have appeared.

The VI-21R-CX-F3 DC DC converter is a high switching frequency, wide input voltage range, and high efficiency isolated DC DC converter. It is developed and manufactured by Zhuohan Technology Co., Ltd. It features integration with an inductor, a rectifier, and a sense resistor, allowing for a more compact design and reducing system costs. It is suitable for applications such as medium and high power applications, automotive, and industrial products.

Application Field

The VI-21R-CX-F3 DC DC converter is mainly applicable for medium and high power applications such as electric vehicles, solar power conversion systems, physical power converters, moveable medical equipment, and so on. It has become the most ideal choice for power module companies and all kinds of system solutions because of its high reliability and scalability.

Working Principle

The VI-21R-CX-F3 DC DC converter is a kind of high efficiency isolated DC DC converter, so its working principle mainly comprises two parts—DC to DC conversion, and DC isolation. During the DC to DC conversion process, the DC input is stepped down to achieve a desired output voltage. In the DC isolation process, the rectifier converts the stepped down DC to pulsating current, which is then rectified and sent to the output circuit. This conversion process allows the DC voltage to be converted from one value to another.

The VI-21R-CX-F3 DC DC converter also features four major components: a power stage, a control stage, an isolation stage, and an output stage. In the power stage, the input voltage is stepped down through a transformer to achieve the desired output through the rectified DC current. The control stage, also known as the controller IC, is used to regulate the output voltage and to protect the converter from over-current and short-circuit conditions. The isolation stage separates the input and the output circuit using isolation capacitors. Finally, the output stage is used to filter out electrical noise from the output current.

Summary

The VI-21R-CX-F3 DC DC converter is a high-efficiency, wide input voltage range, and high switching frequency DC DC converter. It is suitable for medium and high power applications such as electric vehicles, solar power conversion systems, physical power converters, moveable medical equipment, and so on. Its working principle mainly comprises two parts—DC to DC conversion, and DC isolation. Although it features four major components, the power stage, the control stage, the isolation stage, and the output stage. The VI-21R-CX-F3 DC DC converter is still a very efficient device with the highest level of reliability and scalability.
