Integrated matrix transformer module for high-current 48V
This technology is a highly efficient DC-to-DC power converter that combines a specialized transformer design with a multi-channel rectifier into a single compact unit. The 'matrix transformer' links several smaller transformer cores together through shared magnetic plates, which reduces size and spreads the current load evenly. A matched multi-phase rectifier then converts the output cleanly and efficiently. Together, these design choices allow the converter to handle very high currents while running cooler and taking up less board space than conventional designs.
What you could build
A compact, high-efficiency power conversion module targeting hyperscale data center operators, AI accelerator hardware manufacturers, and telecom equipment vendors who need dense, high-current 48V-to-point-of-load conversion at scale.
Who in Virginia should care
Northern Virginia hosts the world's densest concentration of data centers; operators like Equinix, Amazon Web Services, and Microsoft Azure, along with their power supply vendors, would have direct interest in this technology.
