The U.S. International Trade Commission (Commission or USITC) voted to institute an investigation of certain power converters, circuit board assemblies, and computing systems containing the same. The products at issue in the investigation are described in the Commission’s notice of investigation.
The investigation is based on a complaint filed on behalf of Vicor Corporation of Andover, Massachusetts, on January 12, 2026. Supplements to the Complaint were filed on January 21, 23, and 26, 2026.
