DC DC Converters is a type of power converter that can convert a voltage or current from a source of direct current (DC) power to a desired level of output voltage or current. They are important components in ensuring the efficient use of power in a variety of applications, from automobiles to telecommunications to aerospace and military applications. The VI-25V-CX is an example of such a converter and is designed to convert DC voltage from 12V to 24V. In this article, we will look at the application field and working principle of this DC DC converter.

The VI-25V-CX is typically used in automotive and industrial applications, for example, in Hybrid Electric Vehicles (HEV). This particular converter has a high power density, with an efficiency of up to 97%. It is also designed to work in harsh environments, with a low EMI level, making it suitable for EMC-sensitive applications. In addition, it has built-in protection features to guard against over-voltage, over-currents, INL/DNL errors, short-circuit, and so on.

The working principle of the VI-25V-CX is as follows: when the power supply is connected to the converter, it will take in the 12V input voltage from the source, and use a step-down switching regulator to reduce the voltage to 24V. The controller will sense the output voltage, and adjust the frequency of the switching regulator so that the output voltage is maintained. The output voltage can be further regulated by the PFC (Power Factor Correction), which reduces the total harmonic distortion of the output voltage. The converter also contains an over-voltage protection circuit, which can detect if the output voltage is too high, and will shut down the converter if needed.

In conclusion, the VI-25V-CX DC DC Converter is an example of a high-efficiency converter capable of working in harsh environments and controlling a range of output voltages. It is often used in automotive and industrial applications, making it versatile and highly sought-after. Its working principle is based on a step-down switching regulator and PFC (Power Factor Correction) to regulate the output voltage, and an over-voltage protection circuit which can shut down the converter if needed.
