DC-DC converters are electronic devices used to convert direct current (DC) from one voltage to another. Depending on the type of converter, the output voltage can be either higher or lower than the input voltage, allowing them to be used for both power up and down-conversion. In this article, we will discuss the VI-2W1-IV-F1 DC-DC converter application field and working principle.

VI-2W1-IV-F1 Application Field

The VI-2W1-IV-F1 is a wide input range (18-63VDC) two-way DC-DC converter designed for powering monitored systems from a wide range of input voltages. This converter provides well regulated outputs for use in any system that operates on DC power. It is compatible with various systems including industrial automation, relay logic, analog and digital instruments, and I/O circuits. This type of DC-DC converter is particularly suited for applications with non-standard loads and where the input voltage can vary significantly, or where oversized units may be used to replace smaller models.

The VI-2W1-IV-F1 provides an excellent design solution for many applications including:

• Telecommunications
• Data acquisition systems
• Security systems
• Battery back-up systems
• Industrial control systems, and
• Vehicle & industrial electronics

Working Principle

The VI-2W1-IV-F1 converter uses an advanced switching technique to convert the input voltage into DC. It is an isolated module comprising two parts: the primary side and the secondary side. The primary side consists of a power-stage designed to be connected to the input, which consists of an inductor, an element of self-reset, a transistor switch, and a diode as bypass devices; the secondary side includes a power stage designed to be connected to the load, which contains a second element of self-reset, a transistor switch, and a diode as bypass devices.

The main functionality of the converter is provided by a self-oscillating oscillator with pulse-width modulation (PWM). The purpose of the self-oscillating oscillator is to create the needed switching frequency, such as turn the transistor on and off during the load current to transfer energy from the input to the output. When the load is low, the self-oscillaunt oscillator will increase the amount of energy transferred from the input to the output, and vice versa. Also, the PWM is used to regulate the output voltage of the VI-2W1-IV-F1 converter, controlling the voltage without sacrificing efficiency.

In addition, the VI-2W1-IV-F1 is equipped with a protection circuit that monitors the voltages of the input and output to avoid the converter from overvoltage, over-current, or short-circuit conditions. Also, this model has a built-in digital-to-analog converter (DAC) for accurate and repeatable output voltage calibration.

Conclusion

The VI-2W1-IV-F1 is an excellent DC-DC converter for various applications requiring wide input voltage range. It uses an advanced switching technique and PWM control to generate well-regulated output voltages at a high efficiency, while also providing protection against overload and other faults. It is also equipped with a built-in DAC for easy calibration.
