Solving SWaP-C power challenges for MIL-COTS applications Example Applications Products

A need for high-density power solutions

One of the central challenges facing defense industry designers is the ongoing struggle to reduce size, weight, power, and cost (SWaP-C), while at the same time increasing command, control, communications, computing, intelligence, surveillance, and reconnaissance (C4ISR) capabilities. These competing priorities require solutions with ever-increasing power densities and capabilities, while still meeting the stringent reliability, cost, and time-to-market requirements inherent in these demanding applications. A massive increase in power density for DC-DC converters in the MIL-COTS space would enable military designers to spend less of their size and weight budgets on power, and more on the C4ISR capabilities required in their demanding applications. 

Innovating to deliver more power in less space

Vicor continues to raise the bar by delivering technologically advanced MIL-COTS solutions that meet demanding SWaP-C requirements with all the robustness and reliability you would expect from a company that has been selling power conversion products into aerospace and defense applications for more than 30 years. Vicor has a portfolio of power-dense, low weight, low noise, highly reliable modular component families that enable military equipment designers to create SWaP-C optimized solutions. A good example is our DCM™ family of isolated, regulated DC-DC converters. When compared to the next-best solutions in brick packages, our innovative ChiP and ViA packages enable solutions with upwards of 2.5X improvement in power density by volume, and over 3x the power density by weight.
