OCC Creates Simple, Powerful, Elegant

Power Converters and Systems

OCC Company

Founded by Drs. Greg and Keyue Smedley (Caltech PhDs) in August 2004, One-Cycle Control, Inc. manufactures breakthrough power electronics technology for high-performance, high efficiency, and high-density power conversion, creating jobs in California. We envision any power thing has “OCC inside.”

OCC appreciates grants from the federal/state government and early customer engagements that fueled early-stage growth from concept to product. OCC has completed and tested our modular, scalable production lines for volume production in the last three years. We will consider value-added investment opportunities to expand market presence and production capacity.

OCC treasures its employees, customers, suppliers, and partners who make this extraordinary journey possible. Together we have traveled long miles and reached many summits: including delivering the first universal converter to DOE in 2007, a trip to the Pentagon to receive the SBIR Achievement Award in 2010, OCC performance setting a precedent for the smart-inverter standard in 2013, reported by Western Utilities, and an NBC KTVF News showcase of OCC products in 2021, etc.

OCC promotes a collaborative and intellectually stimulating company culture, where employees are encouraged to reach their highest potential. Our world-class team is eager to present you with the world’s premium brand products for your projects.

OCC Technology

Invented at the California Institute of Technology and the University of California, the new-generation DC/DC and 3-phase AC power converter technology attracted interest from the U.S. Department of Energy, the U.S. Department of Defense, the California Energy Commission, and the California Institute for Energy and Environment.

The OCC technology hallmarks include an ultra-fast response that enables our products to track fast commands, quench sharp transients, and reject dynamic disturbances.

High power density is a unique feature that allows our products to fit in commercial server racks, be shipped via commercial carriers, and minimize raw material use.

OCC modular approach facilitates standardized multiple product lines and is scalable for 0-1000 Hz and kVA to MVA applications.

OCC Products

Award-winning premium brand

Developed by world-class power electronics and mechanical experts, OCC products represent extraordinary achievements in power conversion. We are very proud of receiving UCI Innovation Award in 2005 and DOD Achievement Award in 2010. As one of the only 11 teams in the US selected from 471 eligible projects, the DOD award recognized OCC as the best in power electronics. OCC products are made in California with >95% domestic supply chain. A rigorous vendor selection and approval process warrant 100% authentic parts. Our rigid quality control per industry and mil standards translates to premium quality. Furthermore, our products are backed by a two-year warranty.

Environmentally-conscious design

A persistent effort has been put into our product's design to reduce and minimize raw material use while increasing and maximizing energy efficiency, which minimizes mining activities, energy consumption, transportation traffic, manufacturing floor space, and carbon footprint. By using OCC products, together, we create a cleaner and better world.

Made in USA with domestically sourced materials

Power electronics is essential for all consumer, communication, computation, industrial, transportation, defense, and space applications. Presently, most power electronics products sold in the US today are imported. OCC is a premium domestic brand in power electronics and sources materials domestically, helping boost US technical competitiveness, enhance the US economy, and create more US jobs. We do it one power converter at a time.
