DC to DC converters are essential for energy converters and many common applications, especially those requiring a consistent and reliable power supply for sensitive electronic systems. The VI-25V-CW-F1 DC to DC converter is one such device, providing a precise voltage source for equipment needing a stead voltage source or for providing a step-up voltage supply from lower voltage supply sources (9-36V DC input). This makes the VI-25V-CW-F1 a very useful and versatile device for modern applications.

Applications of the VI-25V-CW-F1 DC to DC Converter

The output range of the VI-25V-CW-F1 makes it well-suited for various applications where a steady voltage supply is essential. These include safety and navigation systems, medical equipment, drones, remote systems, LED lighting applications, and various industrial systems. To ensure the utmost safety for the device, its design includes over-voltage, over-current, and reverse connection protection. It also features an active PFC function and is compliant with EMC standards.

Working Principle of the VI-25V-CW-F1 DC to DC Converter

The VI-25V-CW-F1 is a switched-mode power supply (SMPS) designed to supply output voltages in the range of 25.2 to 34.8V DC. It uses a DC-DC step-down transformer as its main component and includes a pair of MOSFET transistors and a couple of Schottky diodes. The MOSFET transistors are mainly used for power conversion, while the Schottky diodes are used for rectification. AC mains, typically 100~240VAC, enters the power supply through an input connector, and is then rectified and filtered by the diode bridge rectifier to produce DC voltage. This DC voltage is then transformed by the transformer to produce the required output voltage.

The switching is carried out by the two MOSFET transistors. At each switching cycle, one transistor is switched on by the PWM control circuit to begin the conversion process. The energy released by the transistor is stored in the transformer core, which with the help of the mains voltage builds up the required output voltage. The other transistor is then switched on to extract the stored energy from the transformer core to the output. This process is repeated in every switching cycle to maintain a steady output voltage.

Conclusion

The VI-25V-CW-F1 is an excellent choice for applications that require a reliable and precise output voltage from an input with a wide range of voltages. It is ideal for applications that require a steady DC voltage or when a higher voltage output is needed from a lower voltage source. It also features protection for over-voltage, over-current, and reverse connection for the utmost safety. Its configurable design and wide range of features make it an ideal choice for many industrial and consumer applications.
