Advanced Science and Technology Solutions

DTI’s PowerMod™ technology delivers the revolutionary advantages of solid-state high power switching to demanding pulsed power and power conversion applications. DTI’s solid-state switches are built from a series stack of IGBTs configured for very high voltage standoff and operated as a single switch. Highly synchronized gate drives ensure the load on the switch is shared equally between devices. The entire switch can be closed or opened in less than a microsecond, safely disconnecting the load in the event of an arc. Each switch is fully isolated from ground and can open without damage under fault currents up to 20 kA. 

DTI provides compact, rugged, reliable, and efficient turn-key transmitter systems and radar retrofits for a wide range of fixed and mobile radar applications. Meeting the most demanding military and commercial requirements, DTI’s solutions are fully solid-state, utilizing high performance power supplies, pulse modulators, voltage regulators, and state of the art control systems. 

DTI’s primary product line is solid state pulsed power systems. This technology represents a revolution in high voltage power – for the first time, allowing high voltage, high power systems to use solid state devices in place of large vacuum tubes or gas discharge switches. Since our initial developments nearly a decade ago, DTI has received numerous patents on this technology and sold over 300 solid state, high voltage modulators, power supplies, and transmitters for a wide range of Government/Military and commercial applications, including radars, particle accelerators, and industrial processes such as semiconductor manufacturing. 

The Regional Scale Nodes (RSN) project is an ambitious effort to provide unprecedented power (10 kW at 10 kVDC) and bandwidth (10 Gbps) to each of several scientific hubs on the seafloor. Led by the Consortium for Ocean Leadership and the University of Washington, and part of the greater NSF Ocean Observatories Initiative, the network consists of a shore station located in Pacific City, Oregon, ~900 km of undersea high power and high bandwidth cable, and seven underwater power distribution terminals. These terminals, called Primary Nodes (sidebar), are located at depths up to 3500 m (2.2 miles) and house DTI power conversion technology, which enables power transfer at 10 kVDC to an array of instruments, providing continuous acquisition of real-time data in one of the world’s most inaccessible, difficult-to-study environments.
