DC DC Converters

DC DC converters are a type of electronic device that allows for the conversion of a DC voltage level to a different DC voltage level. DC DC converters are used in a number of applications, including automobiles, aircrafts, embedded and industrial systems, medical devices, renewable energy sources, and more. One such DC DC converter is the VI-24W-CW, which will be the focus of this article and will explain its application field and working principle.

Application Field

The VI-24W-CW is a brick-style DC DC converter, designed for providing reliable voltage conversion in a wide variety of applications. This DC DC converter is rated for a maximum load of 24W and is suitable for operating temperatures ranging from -40°C to +100°C. It features a wide 4:1 input from 9-36VDC, and can be used to provide a 3.3, 5, 12, or 24VDC output, depending on the model. The VI-24W-CW is commonly used in industrial and embedded systems, such as server networks, CCTV systems, and robotics. It is also used in motor controls, inverters, telecom base stations, microprocessor controllers, and other applications that require a stable DC voltage source. The device is specified for several standards, including vibration and shock.

Working Principle

The operation of the VI-24W-CW is based on the pulse-width modulation (PWM) of a Buck converter. A Buck converter is an electronic circuit that is used to step-down voltage from one level to another. The VI-24W-CW converts the input voltage to a different voltage level through PWM, allowing it to serve as an efficient DC DC converter. The Buck converter is composed of a switching element (usually a transistor or FET), an inductor, and two capacitors. An input voltage is applied to the Buck converter, which is then switched on and off at a regulated frequency. The duty cycle of the switching element is regulated, allowing for a stable and accurate output. The switching of the switching element causes a current to flow through the inductor, which in turn stores energy. The two capacitors help to filter out any noise and ensure a smooth output voltage. Once the energy has been stored in the inductor, it is then released back to the output, providing the output voltage. The switching frequency and duty cycle can be adjusted to provide different output voltages. This allows the VI-24W-CW to provide output voltages from 3.3V, 5V, 12V, and 24V, depending on the model.

Conclusion

The VI-24W-CW is a brick-style DC DC converter used for providing reliable voltage conversion. It is suitable for a wide variety of applications, such as industrial and embedded systems, motor controls, inverters, and telecom base stations. The device is specified for several standards, including vibration and shock. The VI-24W-CW works by pulse-width modulation with a Buck converter, allowing for a stable and accurate output. Adjusting the switching frequency and duty cycle of the Buck converter allows for different output voltages from 3.3V, 5V, 12V, and 24V, depending on the model.
