DC DC Converters

DC DC Converters are increasingly becoming important as they offer extremely reliable power conversion operations for a wide range of applications. The VI-26D-EX is a popular DC DC converter from Vicor Corporation that is designed to provide efficient, reliable, high quality power conversion operations with a wide range of operating temperatures.

Application Field of VI-26D-EX

VI-26D-EX is a DC to DC converter specifically designed to meet the stringent requirements of military and aerospace applications. This converter offers excellent efficiency in a compact package, making it suitable for space-constrained applications. It is capable of providing high quality, highly reliable power conversion for applications that require accurate voltage regulation, including telecom systems, data centers, instrumentation, as well as medical and mobile applications. This converter is also suitable for use in high temperature environments, offering high efficiency even at elevated temperatures.

Working Principle of VI-26D-EX

The VI-26D-EX makes use of the flyback power converter topology. It consists of a power supply core, made up of primary and secondary windings, as well as of an integrated control circuit. The primary winding of the core is connected to the input DC power supply, while the secondary winding of the core is connected to the load. The control circuit monitors the output voltage, and when it is low, it energizes the primary winding. This induces a voltage at the secondary winding, which is then stepped up or down to provide the required output voltage for the load. The control circuit then shuts off power to the primary winding, until the output voltage drops again, at which point the control circuit energizes the primary winding again.

In addition, the VI-26D-EX has an over-current protection circuit which protects the module from overloads and helps to prolong the lifetime of the unit. It also includes a short-circuit protection circuit, which prevents the unit from being overloaded and helps to ensure reliable power conversion operations. The VI-26D-EX also has a built-in temperature sensor, which can detect when the module temperature is too high, and automatically lowers the output voltage before damaging the unit.

Conclusion

The VI-26D-EX DC DC converter from Vicor Corporation is an excellent choice for applications requiring high quality, highly reliable power conversion operations. Its flyback power converter topology makes it highly efficient and compact, while its various protection circuits help to ensure reliable operation. Its wide operating temperature range also makes it suitable for use in harsh environments. As such, it is an ideal choice for military and aerospace applications, as well as for telecom systems, data centers, instrumentation, and medical and mobile applications.
