Who’s working on power electronics and wide-bandgap devices?

Silicon carbide and gallium nitride devices are moving power conversion into electric vehicles, data centers and the grid, and the open problems are in packaging, reliability, gate drive and control. This page shows how much of that work the Helikon Research Graph holds and gives you a problem statement to run in Partner Search.

12,000+

U.S. patents

Counts from the Helikon Research Graph on 13 October 2026, rounded down. Each figure is counted on its own, so they aren’t added together.

How these were counted

Publications: papers whose title, author names or research topics match the keyword set below, the same text the Literature search reads.
U.S. patents: granted U.S. patents whose text matches the keyword set and that carry at least one of these CPC subclasses: H02M, H02P, H02J, H01L, H10D, H03K. That is the Patents search with the CPC subclass field set.
Researchers: people in the graph who authored a matching publication or are named inventors on a matching patent.
Keyword set: "power electronics" OR "power electronic converter" OR "power converter" OR "DC-DC converter" OR "DC/DC converter" OR "DC-AC inverter" OR "multilevel inverter" OR "multilevel converter" OR "traction inverter" OR "grid-tied inverter" OR "motor drive" OR "resonant converter" OR "power factor correction" OR "solid-state transformer" OR "wireless power transfer" OR "power module" OR "power semiconductor" OR "power MOSFET" OR "SiC MOSFET" OR "silicon carbide MOSFET" OR "silicon carbide power" OR "SiC power" OR "GaN HEMT" OR "GaN power" OR "gallium nitride power" OR "GaN transistor" OR "wide-bandgap power" OR "wide bandgap power" OR "IGBT"

Try it on a real problem

Partner Search ranks researchers against a problem statement by what their publications, patents and profiles say. This one’s ready to run. Edit it to fit your project.

We're moving our 800 V traction inverter from silicon IGBTs to SiC MOSFETs, and switching losses and EMI at high dv/dt are worse than our models predicted. Looking for a group with SiC gate drive design, double-pulse testing and power module packaging for thermal cycling reliability.

Who’s working on this

Electrical and computer engineering groups at universities, national laboratory power electronics programs, and company teams in semiconductors, automotive, industrial drives, renewable energy and consumer electronics. The largest companies hold far more patents than they publish, so the patent lists lean toward industry.

From the Helikon Research Graph on 13 October 2026. Researchers are people now at the organization who authored a matching publication or are named inventors on a matching patent. Publications are matching publications that list the organization among their authors’ affiliations at the time of publication, counted once each. Patents are matching U.S. patents the organization owns. Each name opens the organization’s page on Helikon Labs.
