VE-25V-IV-F1

DC/DC converters are an essential component for most electronic systems. They are used to provide a stable power source to sensitive electronic devices, often offering a wide range of output voltages and operating frequencies. In most cases, these devices are used to provide an adjustable output voltage from a fixed input voltage. One of these devices is the VE-25V-IV-F1.

The VE-25V-IV-F1 DC/DC converter is a non-isolated isolated step-down converter, which can deliver up to 25 Watts of continuous power. It utilizes an adjustable output voltage range of between 0 and 25V. The device operates with a switching frequency of up to 150kHz, giving it a high efficiency of up to 90.3%. It is composed of a single active bridge configuration.

Application field

The VE-25V-IV-F1 is ideal for applications where a low-noise power source is required, such as medical device power supplies, high-end embedded systems, communication systems and power module designs. It is also suitable for low-noise supplies in industrial, automotive and military environments.

Other applications that this DCDC converter is ideal for include CCTV surveillance systems, IP camera power, and non-isolated PoE Solutions. Furthermore, applications where the noise generated by the converter itself is a concern can benefit from the VE-25V-IV-F1 due to its low noise performance.

Working principle

The VE-25V-IV-F1 DC/DC converter works using a bridge rectifier circuit, which is composed of two thyristors operating in series when operating at low switching frequencies. This rectifier circuit produces a pulsed direct current (DC) output which is then regulated to the required output voltage by the tri-state control of these two thyristors.

The primary power stage of the converter is then able to control the primary input voltage more accurately by modulating the switching frequency, thus increasing the efficiency of the device. To protect against overload and overvoltage, the VE-25V-IV-F1 contains an advanced EMC filter, which helps ensure the compliance to the relevant standard. The device also has protection against short-circuit and over-temperature.

Conclusion

The VE-25V-IV-F1 DC/DC converter is ideal for applications where a low-noise, efficient power source is needed. It is composed of a bridge rectifier circuit and offers adjustable output voltages from 0 to 25V with a rated power of up to 25W. Furthermore, it features advanced EMC filter technology and protection against overloads and over-voltage.
