DC DC Converters

DC–DC converters are electronic circuits, generally consisting of semiconductor devices, that convert direct current (DC) from one voltage level to another. They are used variously to generate or increase the voltage level, to decrease it, and to provide electrical isolation between circuits.The VI-B21-CW converter is a space-saving DC–DC converter that is cost-effective, reliable, and easy to use. It operates on a wide input voltage range making it well suited for a wide variety of applications.

Application Field

The VI-B21-CW converter is ideal for use in industrial, commercial, and consumer applications as it is suitable for applications in uninterruptible power supplies (UPS), rectangular waveforms, DC-DC converters, and for circuit-breaker applications.One of the most common applications for this converter is in powering electronic equipment from an alternative source such as a battery or wall plug without the need for an external source of power. This is especially useful in portable or mobile situations.It can also be used to provide a steady, reliable voltage and current to various electronic circuits, such as those used in medical equipment, as well as for improving the accuracy of a voltage output from a power supply.

Working Principle

The VI-B21-CW converter works by taking an input voltage of up to 24V and converting it to an output voltage of 3.3V. The process is accomplished via a switching voltage regulator controlled by an on-board microprocessor.The input voltage is rectified through a step-down converter to a DC voltage that is regulated by the switching voltage regulator. This voltage is then used to control an oscillator that produces an output voltage of 3.3V, which is then sent to the output terminals.The output voltage and current can be adjusted by adjusting a parameter called the duty cycle. This is controlled by the on-board microprocessor and is used to adjust the output voltage and current for the optimal performance of the device.

Conclusion

The VI-B21-CW converter offers a space-saving, cost-effective, reliable, and easy-to-use solution for a wide range of applications. It is suitable for applications such as uninterruptible power supplies (UPS), rectangular waveforms, DC-DC converters, and circuit-breaker applications to name a few. It works by taking an input voltage of up to 24V and converting it to an output voltage of 3.3V via a switching voltage regulator controlled by an on-board microprocessor. The output voltage and current can be adjusted using the duty cycle control.
