DC DC Converters -VE-25F-CU Application Field and Working Principle

DC-DC converters provide solutions for various applications by changing the output voltage either up or down from the input voltage. DC-DC converters, such as the VE-25F-CU from South Electronics, allow you to transfer the energy from a DC source, such as a battery, to a downstream load. Depending on the load requirements, the VE-25F-CU can be used to boost the output voltage or decrease it to the correct value. Examples of typical applications include industrial, automotive, telecommunications, and consumer.

Application Field

The application field of the VE-25F-CU varies depending on the downstream load requirements. One of the most popular applications of this DC-DC Converter is its use in automotive electronics. The VE-25F-CU can be used to turn a 12V or 24V car battery into a 13.2V or 14.4V DC power source for gaming consoles, TVs, air conditioning, car CD player, GPS navigation, etc. It can also be used for powering other small appliances, such as air pumps, LED lamps, sounders, contactless card readers, etc.

In industrial applications, the VE-25F-CU is commonly used to transform the battery voltage of a forklift truck into the necessary voltage for the motor controller or the load. It can also be used as a voltage converter for electric vehicles or to power other types of industrial machinery. In telecommunications applications, the VE-25F-CU can be used to boost the voltage of an LTE base station up to a higher voltage.

Working Principle

The VE-25F-CU is a DC-DC buck converter with a wide voltage range input, (6V to 32V) and fixed 12V to 28V output. It has an adjustable voltage output range and an efficiency of 95%. It can supply a maximum of 25A at an output voltage of 24V. It also comes with a number of features such as thermal protection, overload protection, under-voltage protection, and short-circuit protection.

The VE-25F-CU works by converting the input voltage to the required output voltage. To do this, the circuit uses a switch (usually a MOSFET) and an inductor. When the switch is in the ON state, the inductor stores energy in the form of a magnetic field. When the switch is in the OFF state, the magnetic field collapses, resulting in a voltage drop across the inductor. This voltage is equal to the output voltage of the converter. The output voltage can be controlled by adjusting the duty cycle of the switch.

Conclusion

The VE-25F-CU is a popular DC-DC buck converter with a wide input voltage range and adjustable output voltage range. It has a high efficiency of 95% and can supply up to 25A of current at an output voltage of 24V. It is suitable for automotive, industrial, telecommunications, and consumer applications. It works by converting the input voltage to the required output voltage. The output voltage is controlled by adjusting the duty cycle of the switch.
