DC-DC Converters

DC-DC converters are designed to convert a DC voltage to a higher or lower DC voltage, usually within the power supply range of 0 to 250 V. They are commonly used in automotive, solar and power grid systems. Depending on the application, they can be divided into two categories - isolated, non-isolated and regulated converters. In this article, we will look at the application field and working principle of the VE-251-CY-F4 DC-DC converter.

Application Field of VE-251-CY-F4 DC-DC Converter

The VE-251-CY-F4 DC-DC converter is a non-isolated, high performance converter. It can convert a DC input voltage from 0 to 250 V to a regulated DC output voltage of 0.8, 1.5, 3.3, 5, 12, 15 or 24 V. It also has an adjustable input voltage range and a wide temperature range of -40℃ to +100℃. It is ideal for a wide variety of applications including industrial automation, communications, datacom, instrumentation, embedded computing, healthcare, railway and solar.

Working Principle of VE-251-CY-F4 DC-DC Converter

The VE-251-CY-F4 DC-DC converter works by using pulse width modulation (PWM) to regulate its output voltage. PWM is a type of digital signal processing in which the frequency of the signal is kept constant while its pulse width is varied. By varying the pulse width, the output power and voltage can be precisely controlled. The converter also uses synchronous rectifiers to reduce losses and improve efficiency.

The VE-251-CY-F4 DC-DC converter is designed to deliver high power conversion efficiency of up to 96%. To achieve this, the converter uses synchronous rectifiers instead of diodes in the input stage of the converter. Synchronous rectifiers are much faster than diodes and require less input current, leading to decreased power losses and increased power conversion efficiency. The converter also employs temperature compensation techniques to provide better thermal performance and enable the converter to perform under extreme temperatures.

The VE-251-CY-F4 DC-DC converter has a wide input voltage range of 0 to 250 V, making it suitable for a variety of applications. It also supports overvoltage, undervoltage, over-temperature and short circuit protection to keep the system safe. Finally, the converter is RoHS2 compliant, meaning that it is free of hazardous substances such as lead, mercury, cadmium and more, making it an environmentally-friendly product.

Conclusion

The VE-251-CY-F4 DC-DC converter is a high performance, non-isolated converter that can convert a DC voltage from 0 to 250 V to a regulated DC voltage of 0.8, 1.5, 3.3, 5, 12, 15 or 24 V. It is designed to deliver high power conversion efficiency up to 96% and is compliant with RoHS2 requirements. It is ideal for a wide variety of applications including industrial automation, healthcare, railway and solar.
