Aegis Power Systems

Aegis Power Systems is a U.S.-based designer and manufacturer of rugged power electronics for advanced defense systems. Since 1995, the company has developed AC-DC, DC-DC, DC-AC and bidirectional power-conversion solutions for mission-critical applications in the land, air, sea and underwater domains.

The company provides standard commercial off-the-shelf products, modified-COTS configurations and fully custom systems for weapons, directed energy, radar, counter-UAS, communications, embedded computing and other high-demand military equipment. All Aegis products are produced in the United States, enabling the company to meet a variety of Made in the USA requirements for defense procurement and supply-chain security.

Military-grade power electronics for mission-ready systems

Aegis has broad and deep experience with the electrical and environmental standards that govern integration into military platforms, including MIL-STD-810 environmental and shock requirements, MIL-STD-461 electromagnetic interference requirements, MIL-STD-1275 ground-vehicle power, MIL-STD-704 airborne power and MIL-STD-1399 shipboard power.

The company is ISO 9001:2015 and AS9100D:2016 registered, ITAR registered and IPC certified, ensuring that all products are delivered with the utmost in quality.

High-Power Conversion for Weapons, Radar & Counter-UAS

Aegis develops rugged military AC-DC power supplies and high-power converters that transform available platform power into stable outputs for weapons, radar, sensing, counter-UAS and directed-energy systems.

Solutions can be engineered to provide single or multiple outputs, electrical fault protection, sealed enclosures and the thermal management required by the specific installation.

VPX Power Supplies for Modular Open Systems

Aegis develops high-density VPX power cards for interoperable embedded computing systems used in mission computing, radar, electronic warfare, communications and electro-optical sensing. These applications may incorporate high-performance processors, GPUs and other AI-enabled computing hardware, creating greater demands for efficient power conversion within tightly constrained card slots.

Bidirectional Power Conversion

Aegis’ bidirectional conversion solutions manage power across high- and low-voltage systems, enabling energy to move between battery systems, vehicle power architectures and mission payloads.

The product portfolio includes high-voltage DC-DC and DC-AC solutions for ground vehicles, autonomous platforms, naval systems, future airborne applications and more. Designs can incorporate liquid cooling, CAN bus communications, sealed enclosures and military connectors, allowing the power electronics to be integrated directly into mobile platforms and outdoor systems.

Multi-Domain Power Supplies for Military Platforms

Military power supplies must accommodate very different source characteristics and environmental conditions depending on whether they are installed on a ground vehicle, aircraft, surface vessel or undersea system. Aegis has extensive experience designing to a wide range of standards for domain-specific requirements, including MIL-STD-1275 transients for vehicle power, MIL-STD-704 aircraft power and MIL-STD-1399 shipboard electrical systems.

Products can also be configured to withstand extremes of shock, vibration, temperature extremes, moisture and electromagnetic interference. Environmental protection and enclosure options can be developed for exposed, naval and undersea environments, and conduction, forced-air, baseplate and liquid-cooling approaches allow thermal performance to be matched to the host system.

Modular & Custom Defense Power Engineering

Aegis’ modular development strategy enables the company to develop solutions to requirements that cannot be met by a standard military COTS power supply. Existing circuits and proven power-conversion modules can be combined or modified to create new product variations with program-specific inputs, outputs, power ratings and control features.

Customers can specify the required AC-DC, DC-DC, DC-AC or bidirectional architecture, along with form factor, connectors, communications interfaces, cooling method and environmental protection. Aegis can then recommend an existing COTS product, modify a current design or develop a custom unit based on suitable internal technology. This gives system integrators a route to specialized power conversion without starting from a completely unproven design.
