Vicor Corporation
American manufacturer of modular power components and power systems for demanding electronic applications.
Last updated August 22, 2026
Overview
Vicor Corporation is a United States-based power-electronics company headquartered in Andover, Massachusetts. Incorporated in 1981, the company designs, manufactures, and markets modular power components and complete power systems. Its products convert electrical energy from sources such as utility-powered alternating current, batteries, rectifiers, or high-voltage direct-current distribution systems into the regulated direct-current voltages and currents required by electronic circuits. The company's business is centered on modular power conversion rather than on finished consumer electronics. Vicor's components are intended to help equipment manufacturers manage power density, efficiency, thermal performance, size, and system integration. Its portfolio is associated with modular architectures such as the VI Chip family and Picor products, which are used as building blocks within larger electrical and electronic systems. Depending on the application, Vicor products can support intermediate bus conversion, point-of-load regulation, power distribution, and broader power-system functions. Vicor serves business-to-business customers across a diverse set of sectors. The applications identified for its products include telecommunications, computing and data-center infrastructure, industrial equipment and automation, robotics, automotive systems, vehicles and transportation, unmanned aerial vehicles, satellites, and aerospace and defense equipment. These markets generally require reliable power conversion in constrained spaces or under demanding electrical, mechanical, and environmental conditions. Vicor therefore positions itself around high-performance, compact, and modular power solutions rather than commodity power supplies. The company sells in North and South America and reaches international customers through its own overseas entities and independent distributors. Its corporate and operating structure includes subsidiaries or affiliated entities in Germany, France, Italy, Hong Kong, the United Kingdom, Japan, China, and the United States. This international footprint supports sales, customer engagement, development, and corporate operations across major electronics markets. Patrizio Vinciarelli has been identified as Vicor's founder and, in the cited reference material, serves as chair of the board, president, and chief executive officer. Vicor is publicly traded on the Nasdaq under the symbol VICR. The company remains an active specialist supplier whose products are primarily embedded inside larger electronic, computing, industrial, transportation, and aerospace systems rather than sold directly to mass-market consumers.
History
Vicor Corporation was incorporated in 1981 in Andover, Massachusetts, with Patrizio Vinciarelli identified as its founder. From its beginning, the company has focused on power conversion: transforming electricity supplied by a mains connection, battery, rectifier, or high-voltage direct-current distribution network into the specific direct-current power required by electronic circuits. Rather than concentrating on complete end-user devices, Vicor developed a business around modular power components and integrated power systems. This approach allows equipment manufacturers to assemble power architectures from standardized or configurable conversion blocks. The company's products are intended to address engineering requirements such as electrical efficiency, power density, thermal management, packaging, and system-level integration. Vicor's portfolio became associated with modular power-conversion architectures, including the VI Chip family and Picor products. These product families serve as building blocks for applications that may require intermediate-bus conversion, point-of-load regulation, or other stages in the movement and conditioning of electrical power. The company has marketed its technology to manufacturers in telecommunications, computing, industrial automation, robotics, automotive and transportation, unmanned aircraft, satellites, and aerospace and defense. As its commercial reach developed, Vicor expanded beyond the United States through a combination of international subsidiaries and independent distribution. The company sells across North and South America and internationally. Reference material identifies entities in Germany, France, Italy, Hong Kong, the United Kingdom, Japan, China, and the United States. This network reflects Vicor's role as a business-to-business component supplier serving global electronics and equipment manufacturers. Vicor is publicly listed on Nasdaq under the ticker VICR. The cited corporate information identifies Patrizio Vinciarelli as chair of the board, president, and chief executive officer. As of 2022, the company had 11 subsidiaries or legally domiciled affiliated entities, including Vicor GmbH in Germany, Vicor France SARL, Vicor Italy SRL, Vicor Hong Kong Ltd., Vicor U.K. Ltd., Vicor Japan Company Ltd., Vicor KK, Vicor Trading (Shanghai) Limited, Vicor Development Corporation, Freedom Power Systems, Northwest Power, and 560 Oakmead LLC. Vicor remains an active specialist manufacturer whose technologies are embedded in larger electronic and power systems across commercial, industrial, transportation, and aerospace markets.

Products and positioning
High-performance, modular power-conversion solutions for compact, efficient, and demanding electronic systems.
VI ChipModular power-conversion components
The VI Chip family is a modular power-conversion architecture used as a building block in larger electronic power systems. VI Chip products can support stages such as intermediate-bus conversion and power distribution, allowing equipment designers to build compact power architectures around modular components. The family is associated with Vicor's emphasis on high power density, efficiency, and system integration for demanding commercial, industrial, computing, transportation, and aerospace applications.
PicorPower-management and conversion components
Picor products form part of Vicor's power-management portfolio and are used in power-conversion and regulation functions within electronic systems. They are intended for designers requiring modular solutions for conditioning and delivering power to circuits and subsystems. The family supports Vicor's broader business in telecommunications, computing, industrial automation, robotics, transportation, and other applications where efficient and compact power management is important.
Complete power systemsIntegrated power systems
In addition to individual modules, Vicor designs and markets complete power systems assembled around its modular conversion technologies. These systems address the conversion of power from sources such as AC mains, batteries, rectifiers, or high-voltage DC networks into the regulated DC power required by electronic equipment. They are aimed primarily at business-to-business customers integrating power into larger products and infrastructure.
