Aegis Power Systems

Aegis Power Systems is a U.S.-based designer and manufacturer of rugged power electronics for marine and naval systems. For over 30 years, the company has developed AC-DC, DC-DC, DC-AC and bidirectional power-conversion solutions for a wide variety of applications including surface vessels, undersea equipment, marine electronics racks, and electric and hybrid propulsion.

The company’s offerings include standard commercial off-the-shelf products, modified-COTS configurations and fully custom systems. Many designs can be operated in parallel to increase available power or provide redundancy for critical onboard equipment.

Marine-grade power electronics for demanding ocean environments

Aegis has extensive experience with the electrical and environmental requirements that govern integration aboard ships and marine platforms. This includes MIL-STD-1399 shipboard power, MIL-STD-461 electromagnetic interference, MIL-STD-810 environmental conditions and MIL-STD-901 high-impact shock.

Available packaging includes open-frame, rackmount, slide-in and sealed enclosures. Convection, forced-air, baseplate and liquid-cooling options allow thermal performance to be matched to the installation, and anti-corrosive conformal coating can protect circuit boards against salt and splash. All Aegis products are manufactured in the United States.

Shipboard Power Supplies & Rectifiers

Shipboard electrical systems require stable conversion from vessel power to the DC voltages used by communications, control, sensing and other electronic equipment. Aegis supplies single-phase and three-phase AC-DC power supplies for naval and commercial marine installations, with scalable output, rugged packaging and application-specific electromagnetic and environmental protection.

Marine Electronics & Rackmount Power Systems

Marine electronics racks on board vessels and other platforms may combine processors, communications equipment, displays, sensor interfaces and control hardware, each with different voltage and current requirements. Aegis develops versatile chassis-mount and rackmount power systems with multiple outputs, redundancy and remote-monitoring options for naval and marine equipment installations.

VPX Power for Marine Computing & Sensor Systems

Aegis develops high-density VPX power cards that convert platform DC power into the regulated outputs required by processors, GPUs and other embedded computing hardware used in modular open architectures.

Electric & Hybrid Marine Propulsion

Electric boats and hybrid vessels combine high-voltage batteries or DC buses with conventional low-voltage electronics, control systems and auxiliary loads. Bidirectional conversion allows energy to move seamlessly and reliably between these architectures as operating conditions and power-management priorities change.

Subsea, ROV & Shore Power Conversion

Undersea vehicles, tethered ROVs, seabed instruments and subsea communications systems may require high-voltage transmission followed by local conversion to the lower voltages used by onboard electronics and payloads. Aegis can adapt its AC-DC and DC-DC building blocks for the inputs, outputs, enclosures, connectors and thermal architectures required by these applications.

Aegis’ technology is also ideal for shore-power converters, battery chargers and DC-bus conditioning systems used alongside vessels and marine equipment. Power-factor correction, parallel operation, redundant configurations and remote monitoring can be incorporated where required by the installation.

Modular & Custom Marine Power Engineering

Aegis’ modular development strategy enables the creation of specialized marine and naval power solutions that go beyond the capabilities of standard COTS products. Existing circuits and proven power-conversion modules can be combined or modified to create variations with platform-specific inputs, outputs, power ratings, communications and control features.

Customers can specify the required AC-DC, DC-DC, DC-AC or bidirectional architecture, along with form factor, connectors, monitoring, cooling method and environmental protection. Aegis can then recommend an existing product, modify a current design or develop a custom unit suited to the vessel, undersea system or shore installation.
