DTI's PowerMod Technology is at work in power conversion applications.

DTI’s 400 Hz weapons power converter was designed to satisfy the Navy’s requirement for a “drop-in” replacement of its baseline power converters used on the Virginia class submarine.The power converter operates at a switching frequency of 50 kHz. The higher control bandwidth provided by high frequency switching allows the output power to be highly regulated into nonlinear and transient loads. It is a potential retrofit for power converters on the Seawolf and 688 classes of submarines. This technology can also be applied to variable frequency power converters, such as those needed for synchronous AC motor drives, where high reliability and low acoustic noise emission are of the utmost importance.

The PowerMod™ Modular DC-DC Power Converter is a revolutionary concept in powering 48V DC servers and switches. It offers efficient distribution of 425 – 600 VDC power with down-conversion at the Point-of-Load (POL); direct DC – DC conversion at high power levels; modular construction, configurable from 10 kW – 150 kW per rack; and full system redundancy and ride-through from multiple power sources.

DTI's universal power converter architecture can be used for a wide range of applications requiring AC-to-DC and DC-to-DC power conversion. Scaling this technology to higher voltage (tens of kV) and higher power (MWs) opens entirely new applications such as DC-to-DC converters for high voltage DC undersea networks and power conditioning systems for driving pulsed power systems.
