What Advanced Conversion Technology does

Advanced Conversion Technology (ACT) is a U.S.-based, employee-owned designer and manufacturer of military-grade AC-DC and DC-DC power supplies and inverters, founded in 1981 and headquartered in Middletown, Pennsylvania. The company builds both commercial-off-the-shelf units (spanning 400W to 9 kW) and fully custom engineered solutions, applying proprietary soft switching (zero voltage switching) technology, active power factor correction achieving greater than 0.99 power factor and less than 3% total harmonic distortion, and multiple thermal management modes (conduction, convection, forced air, liquid, and radiation cooling) optimized via CFD simulation. ACT maintains compliance with MIL-STD-704 (aircraft), MIL-STD-1275 (ground vehicles), MIL-STD-1399 (shipboard), MIL-STD-461 (EMI), MIL-STD-810 (environmental), and MIL-S-901 (shock), along with AS9100D, ISO 9001:2015, and ITAR certifications. Manufacturing is fully vertically integrated under one roof in Pennsylvania, including in-house machining, transformer and choke production, assembly, and MIL-STD-461 pre-compliance testing.

ACT generates revenue through three streams: hardware sales of MIL-COTS power supplies, custom engineering and design services for application-specific requirements, and build-to-print contract manufacturing. Pricing is quote-based and tied to specifications, compliance standards, and volume, with multi-year program contracts typical in the defense cycle. The customer base is concentrated in U.S. defense, spanning all military branches and prime contractors (Harris Corporation is a documented customer and 2018 Small Business Supplier of the Year recipient), with a secondary commercial channel serving mining, petro-chemical, offshore drilling, rail, automotive, and industrial manufacturers seeking MIL-spec-grade durability. Go-to-market is direct enterprise field sales, supported by a website inquiry funnel and regional field sales engineer coverage in states such as TX, AZ, and CA. The company is currently in a leadership transition following the 2024-2025 retirements of CEO Robert Kirker and CEO Tracy Shaffer, with Andrew Domovich assuming leadership in March 2025.
