What The Transformer Association does
The Transformer Association (TTA) is a North American manufacturing trade association founded in 1974 (originally as the International Power Conversion Products Council) and headquartered at 1300 Sumner Avenue, Cleveland, Ohio, operating under association-management parent Thomas Associates, Inc. TTA serves as the voice of the transformer, inductor, and magnetic device industry, forging strategic alliances among manufacturers, industry suppliers, consultants, and safety/regulatory agencies. Its service portfolio includes company-based membership with Board-approved enrollment, signature Spring and Fall industry meetings, virtual events and webinars, a searchable member directory, and a $2,500 scholarship program for students in power conversion design.
The association's principal operating subsidiary-equivalent is the IMA Working Group (International Magnetics Association), formed originally as MMPA in 1959, renamed IMA in 2001, and incorporated into TTA in 2009. IMA develops, maintains, and distributes formal industry standards for soft ferrite cores, including a User's Guide and Standard Specifications for pot, toroid, U/E/I, and threaded cores. TTA monetizes primarily through recurring membership dues, one-time event registration fees, and sponsorships from a diversified set of named industry sponsors (Lenco Electronics, Dongan Electric, EIS, New England Wire Technologies, Triad Magnetics, Essex Brownell, Elantas PDG). Distribution is hybrid: a self-serve website portal for membership information, directory search, and event registration, plus rotating in-person meetings across major US cities.
TTA's customer base is horizontally segmented across transformer manufacturers, industry suppliers, magnetic materials producers and distributors (via IMA), and consultants/regulatory agencies. Geographic scope is North America (USA). The organization has 51-100 employees, no external funding rounds (operating as a dues-funded nonprofit), no disclosed revenue, and no API, SDK, or mobile product. Upcoming 2026 meetings are scheduled in Rosemont, IL (Spring) and Nashville, TN (Fall).

The Transformer Association competitors and assessment
Company assessmentDirect peers
- ABMA – American Bearing Manufacturers Association: U.S. trade association for bearing and motion component manufacturers. Comparable to TTA as a niche U.S. manufacturing trade association funded by member dues, hosting industry events, and conducting statistical programs for a specialized industrial component vertical.
- SMMA – The Motor & Motion Association: Trade association serving manufacturers of electric motors, motion control, and related electromagnetic components. Highly comparable to TTA because it serves an adjacent magnetics/electromagnetic device manufacturing community with a similar model of membership dues, technical conferences, and standards-driven member value.
- ECIA – Electronic Components Industry Association: Trade association for manufacturers and distributors of electronic components. Comparable to TTA because it represents component-level manufacturers and their supply chain with membership dues, conferences, and industry statistics — paralleling TTA's supplier-manufacturer structure.
- Power Sources Manufacturers Association (PSMA): Trade association focused on power conversion and power supply manufacturing. Comparable to TTA because it represents manufacturers of power electronics and conversion products — directly overlapping with TTA's historical roots as the International Power Conversion Products Council.
Broad incumbents
- AMT – The Association For Manufacturing Technology: U.S. trade association representing builders of manufacturing technology and related equipment. Comparable to TTA as an established manufacturing trade association using events (IMTS and others), statistics programs, and member dues to serve a discrete manufacturing vertical.
- IPC International (Association Connecting Electronics Industries): Global trade association for the electronics manufacturing industry, offering standards, training, and events. Comparable to TTA in its standards-driven, member-funded, event-anchored operating model applied to electronics manufacturing.
- AHRI – Air-Conditioning, Heating, and Refrigeration Institute: Trade association representing manufacturers of HVACR equipment. Comparable to TTA as an established industry association using membership dues, standards development, and certification programs to serve a specific equipment-manufacturing vertical.
- NEMA – National Electrical Manufacturers Association: Largest U.S. trade association for electrical equipment manufacturers, covering transformers, switchgear, lighting, and broader electrotechnical products. Comparable to TTA because its transformer manufacturer members overlap with TTA's constituency, but NEMA operates at a much broader industry scope.
Emerging players
- IEEE Power Electronics Society: Technical society within IEEE focused on power electronics research and applications. Comparable to TTA in serving the power conversion/magnetics professional community through conferences, publications, and standards-adjacent activities, though from a technical-society rather than trade-association perspective.
- Power Engineering Society (IEEE PES): IEEE society for power and energy professionals, including transformer and grid applications. Comparable to TTA in engaging professionals across the transformer value chain, though it serves individual engineers via a technical society model rather than companies via a trade association model.
