Like most homes, the power distribution within aircraft has traditionally been AC. However, technology developments have enabled power systems designs to turn towards higher voltage DC distribution systems that can provide greater overall efficiency while simultaneously being more compatible with energy storage (batteries) and load requirements. Yet reliance on AC-DC conversion and distribution is a design approach that inherently multiplies the number of power electronics required – at odds with the principles of Size, Weight, Power, and Cost (SWAP-C) that are so critical to success. The SWAP-C challenge is compounded by exponential growth in the amount of electrical power required onboard aircraft.
More systems are increasingly electric, from more sophisticated cockpit avionics and more electrically actuated systems to creature comforts such as coffee, food service, and entertainment. It’s an upward trend, not only in the amount of power but also in the complexity of overall systems.
