Power Conversion

Custom Power Conversion Solutions

Unparalleled Efficiency & Performance

Marotta’s award-winning, patented power supply and conversion technologies are customized to meet the challenging requirements of commercial and military platforms. Our dedicated and highly experienced electronics engineers design power conversion products that optimize the system envelop and provide our customers with a smaller, lighter and economical solution.

Examples of our electric power systems components are AC/DC and DC/DC power conversion, integrated power conversion with power distribution, and miniaturized power distribution units-for tactical applications. No matter their configuration or function, everything we produce in this category features the same characteristics that make them indispensable in a wide range of applications. Built on a foundation of innovative technology, these units are extremely efficient, reliable and are designed to perform in challenging environments in which precision and durability are mission critical.

We create solutions that include power supplies for high-volume missile programs, electronic controls for next-generation aircraft and high-performance power distribution units for use in hypersonic vehicles.
