Rack-Mounted DC Converters in Aerospace: Powering the Skies

The aerospace industry is a field where high-density power solutions are a key requirement. With the ongoing need to reduce size, weight, power, and cost (SWaP-C), while simultaneously increasing command, control, communications, computing, intelligence, surveillance, and reconnaissance (C4ISR) capabilities, the role of rack-mounted DC converters becomes essential.

Powering Aerospace and Defense Applications

In aerospace and defense applications, the use of high-efficiency, high-density DC converters can double the internal bus power and keep the aircraft as light as possible. These converters also provide a well-regulated 48V at more than 1kW to enable higher peak RF output power. In unmanned aerial vehicles (UAVs), these power delivery systems support more functionality, increasing payload and runtime.

Technological Innovations

Companies like Vicor are raising the bar by delivering technologically advanced MIL-COTS power solutions that meet demanding SWaP-C requirements with robustness and reliability. Their DCM™ family of isolated, regulated DC-DC converters, for instance, offers solutions with upwards of 2.5X improvement in power density by volume, and over 3x the power density by weight, compared to other solutions.

Applications in Satellite Communications

In satellite communications, the use of rack-mounted DC converters enhances onboard voice and data communications by taking advantage of maximized power amplifier efficiency.

Custom Power Solutions for Aerospace

When standard power supply models don't meet the specific needs of a project, companies like Acopian can provide custom power solutions. Their custom power supplies or custom power systems can be designed to meet the unique requirements of aerospace applications. These include rack-mounted, wall-mounted, pluggable and modular configurations, providing redundancy and high reliability.

In conclusion, rack-mounted DC converters are a vital component in the aerospace industry. They help to meet the demanding requirements of this field by providing high-density power solutions, enabling more functionalities, and contributing to the efficiency of various applications. With continuous technological advancements and the ability to provide custom solutions, these converters are truly powering the skies.
