DC DC converters are utilized to resource power from one provenience to a multiple output streams. One of the many popularly used DC/DC converters is the V375A48C400BN2. Below is an overview of its application field and working principle.

Application Field

The V375A48C400BN2 is categorized as a step-down DC/DC converter type and normally used in applications where power supply voltage is required in multiple voltage levels. More precisely, this converter utilizes a 24 VAC/VDC universal input supply for its operation and then step down that voltage to an analogous voltage of up to 400VDC.

Furthermore, its power density is suitable for both distributed and non-distributed power applications. Non-distributed power applications would typically involve one output voltage. This type of configuration is used in many different electrical systems such as industrial, medical and aerospace fields. On the other hand, distributed power applications may need up to four output voltage levels. Therefore, these converters are an optimal choice for multiple-voltage applications.

Working Principle

The V375A48C400BN2 converter uses a synchronous buck converter topology, which involves an inductor, a capacitor, and power transistors. The converter utilizes a high-frequency oscillator for the switching of the power transistors.

When the converter is activated, the voltage from the 24 VAC/VDC input source is directed to an inductor, and then a capacitor is charged. As the switch is activated at a high frequency, the inductor stores this energy and it essentially acts as a filter that smoothens the voltage sine wave from the input source.

As this energy is stored, the switch is opened, and the transformer begins to transfer this energy from the inductor. A feedback regulator will ensure that the output voltage is regulated inside a certain range.

The stored energy in the capacitor is then discharged, which prevents the output voltage from going above the set limits. Consequently, the regulator keeps the output voltage stable and the circuit can be used to provide power to various systems such as telecommunications, industrial control and data processing.

Conclusion

Overall, the V375A48C400BN2 DC/DC converter is a reliable source of power for multiple voltage applications. It utilizes a synchronous buck converter topology and is designed to be used in multiple industries such as industrial, medical and aerospace fields. Furthermore, it is outfitted with a feedback regulator that ensures a constant and stable output voltage.
