DC-DC converters are devices used to convert electrical energy between two discretely different voltages or currents. This type of device is generally used to reduce the voltage of higher voltage systems while maintaining power or to increase the voltage of lower voltage systems while maintaining power. The VI-2WJ-EX converter is one such device that is used both for commercial and industrial applications.

Application Field

The VI-2WJ-EX converter is mainly used in applications where a low voltage output is required and a high voltage input needs to be maintained. The device can handle voltages up to 3600V with up to 600A current. It can also reduce the input voltage to a maximum of 50V, making it suitable for powering a wide variety of low power circuits and devices. It is also suitable for powering telecom systems, industrial equipment, and for use in vehicles for power management systems and other applications.

Working Principle

The VI-2WJ-EX is an isolation DC-DC converter that is based on buck-boost switching topology. This type of converter works by constantly switching the input voltage between a high voltage and a low voltage. This results in the device effectively producing an output voltage which is lower than the input voltage. The device is controlled through a digital interface and the output voltage can be adjusted by changing the duty cycle of the switching cycles.

The device uses a step-up and step-down switching architecture where the input voltage is held at a constant level and only the output voltage is adjusted. This enables the device to maintain its efficiency over a wide range of loads. The output voltage is controlled by a feedback loop which drives the duty cycle of the input voltage, and the loop keeps the output voltage from straying too far from the requested value.

The device also features EMC protection circuitry which helps to reduce the noise generated by the device. This ensures that the device does not interfere with other nearby electronics. This contributes to making the device suitable for applications in sensitive environments such as telecom systems and sensitive automotive electronics.

In addition, the device also features over current protection and over temperature protection. This ensures that the device is safe to use and that it does not suffer any damage during excessive loading or high temperature conditions.

Overall, the VI-2WJ-EX converter is a highly reliable and efficient device that can be used in a variety of applications for voltage and current conversion. The device is designed for a wide range of input and output voltages, making it suitable for a wide range of applications. In addition, the device features various protection features which ensure the device is safe to use and performs efficiently over a wide range of conditions.
