DC to DC converters are electronic components that convert direct current (DC) from one level of voltage to another. The VI-2T2-CX-F1 is a two-terminal, isolated, linear DC to DC converter that is typically used for DC-bus applications such as motor drives and battery-powered systems. This converter utilizes high frequency switching to convert DC power from one voltage level to another.

Application Field

The VI-2T2-CX-F1 converter is designed for applications in the DC-bus. As motor drives are constant and power consumption is high, it is important to supply the DC-bus with the right voltage level. The VI-2T2-CX-F1 converter is capable of providing a reliable and efficient power conversion to the desired DC voltage level. It provides galvanic isolation, allowing the input and output circuits to be completely independent from each other. Furthermore, it is rated for up to ±50V inputs and outputs, perfect for use in motor drives and other power systems.

Working Principle

The converter works by utilizing two high frequency switch transistors to convert an input DC voltage into a finer regulated output voltage. The input DC voltage is applied to the primary coil of an isolation transformer. The two transistors act as switches for current flow, alternately allowing the energy stored in the isolation transformer to be released into the output rectification circuit when the transistors switch on and off. This helps to regulate the desired output voltage while also providing galvanic isolation.

The switching rate of the transistors is controlled by a dedicated oscillator circuit. This oscillator is sensitive to output voltage variations and will adjust the switching rate accordingly. This forms the basis of the feedback loop, where the output voltage is constantly monitored and adjusted to match the desired level.

Furthermore, the VI-2T2-CX-F1 converter also includes a full-protection circuit, protecting both the input and output stages from overcurrent, overvoltage, and overtemperature. This ensures that the converter remains reliable and safe even under extreme operating conditions.

Conclusion

In conclusion, the VI-2T2-CX-F1 is a two-terminal, isolated, linear DC to DC converter that is ideal for use in motor drives and other DC-bus applications. It utilizes high frequency switching to effectively and efficiently convert DC power from one voltage level to another. It includes a full-protection circuit for safety and reliability, and the voltage is monitored by a built-in feedback loop for precise output voltage control.
