DC–DC converters, also known as step-down or buck converters, are common electronic components in many electronic devices. The VI-24X-IV-F4 converter is one such DC–DC converter. This article explains the application field and working principle of the VI-24X-IV-F4 converter.

Application Field of VI-24X-IV-F4

In the general electrification usage, the VI-24X-IV-F4 is used to provide stable direct current output from alternating current input. It is suitable mainly for applications that require high isolation, high performance, and low output noise. This includes robotic systems, automotive industry, and power supplies. The quality assurance of the converter is ensured through its full temperature range operation of -40°C to +85°C.

The VI-24X-IV-F4 is an ideal choice for applications that require high operating efficiency, high power density, and good power output regulation.

Working Principle of VI-24X-IV-F4

The VI-24X-IV-F4 utilizes linear topology, allowing it to accept high voltage inputs and deliver low-voltage adjustable DC output power. The operating principle can be understood in terms of four steps.

1. Input Rectification: The AC input first passes through the input rectifier, and then the diodes reverse the current and send it to the switching field effect transistors (FETs).
2. Voltage Regulation: The field effect transistors (FETs) open and close at a specific frequency, which extracts and positions energy according to the desired output voltage.
3. Efficiency Optimization: The VI-24X-IV-F4 converter utilizes switching frequency and peak current mode control techniques to optimize the efficiency of the power conversion process.
4. Output Regulation: After the power conversion process is completed, the output voltage is regulated via the primary sidacs and secondary BJTs to prevent any voltage fluctuation. The BJTs also provide a path for the circuit to reduce input voltage.

Conclusion

The VI-24X-IV-F4 is one of the most commonly used DC–DC converters in the general electrification usage, suitable mainly for applications that require high isolation, high performance, and low output noise. The converter utilizes four separate steps in its working principle in order to deliver a stable DC output from an AC input. The high operating efficiency, power density, and good power output regulation make the VI-24X-IV-F4 an ideal choice for many applications.
