DC to DC converters are used to step up or step down voltage and to extract power from a DC source. In this article, we will discuss the VI-25F-CU-F2 DC DC Converter and its application field and working principle.

Introduction

The VI-25F-CU-F2 is a DC/DC Converter belonging to the Non-Isolated Gauge Series. It is an isolated DC/DC converter and is available in a variety of voltage configurations to meet the needs of different applications. This converter is capable of transmitting power up to 25 watts. It has an operating temperature range of -20°C to +140°C and is IP65/IP67 rated for indoor and outdoor installation. It has full SELV rated output, over temperature protection, and power FETs. It is also equipped with a very advanced microprocessor that continuously monitors input voltage, output voltage, temperature and current safeguards.

Application Field

The VI-25F-CU-F2 is an ideal DC/DC converter for applications such as charging, voltage regulation, and energy harvesting in battery-operated systems. The application field includes motor and pump drives, high-precision instruments, photovoltaic systems, high-efficiency lighting, and automotive systems. It is especially widely used in outdoor projects and applications with a large voltage input range, such as solar energy, wind energy, and other distributed energy sources.

Working Principle

The VI-25F-CU-F2 follows a fly-back topology, in which the energy is stored in a magnetic field and then converted from DC to the desired output voltage. This process is done through a transformer with two windings, one for the primary side and the other for the output. The power flow in this converter is from the input to the output, where the primary side is connected to the input source, and the secondary side is connected to the output. The transformer is used to transfer the power from one side to another and also to provide electrical isolation.The energy transfer is regulated by two controlled switching elements (usually power FETs). The FETs are switched on and off at certain intervals to control the power delivery and regulate the output voltage. The primary side FET is connected to the output of the control circuitry and is switched according to the input voltage. The secondary side FET is connected to the output of the transformer and it is switched according to the output voltage.

Conclusion

In summary, the VI-25F-CU-F2 DC to DC converter is a highly efficient, reliable, and cost-effective solution for a variety of applications. It has a wide input voltage range, full SELV rated output, and advanced monitoring and protection features. Furthermore, its working principle is based on a fly-back topology where energy is stored in a magnetic field and transferred from the input to the output using controlled switching elements. This makes it an ideal choice for applications that require reliable and efficient DC to DC conversion.
