DC DC Converters: VE-240-CW Application Field and Working Principle

The VE-240-CW is a high-performance, fanless DC DC converter designed for industrial and automotive applications. It is a high-efficiency, hybrid isolated DC DC converter that provides a regulated 48VDC output from a DC source input from 12-18VDC. The VE-240-CW is designed to meet the most demanding requirements for high-current, highly reliable power supplies.

Application Field

The VE-240-CW is suitable for a wide range of applications. It is mainly used in industrial and automotive applications such as factory automation, motor drives, instrumentation, electric vehicle charging, and embedded systems. It is also suitable for use in solar and telecommunication power systems.

Working Principle

The VE-240-CW uses an innovative hybrid topology and state-of-the-art magnetic components to derive a high power-density rating and improved regulation accuracy. The VE-240-CW uses a combination of a full-bridge DC-DC converter and a forward converter. The full-bridge converter is used to isolate the high voltage input from the output, and the forward converter is used to obtain the regulated output voltage from the high voltage input.The output voltage of the VE-240-CW is regulated through the use of a feedback loop. A voltage supervisor continuously monitors the output voltage and sends correction signals to the control circuit. The control circuit then adjusts the duty cycle of the switching transistors in order to maintain the desired output voltage.The VE-240-CW also features over-temperature protection, short-circuit protection, and sine wave current-mode control for improved stability and transient response. The VE-240-CW offers high efficiency of up to 94%, making it highly efficient and cost-effective for many industrial and automotive applications.

Conclusion

The VE-240-CW is a high-performance, fanless DC DC converter designed for industrial and automotive applications. It offers a high power-density rating and improved regulation accuracy, and features over-temperature protection, short-circuit protection, and sine wave current-mode control for improved stability and transient response. The VE-240-CW also has a high efficiency of up to 94%. It is an ideal choice for factory automation, motor drives, instrumentation, electric vehicle charging, embedded systems, solar and telecommunication power systems.
