What Advanced Conversion does

Advanced Conversion (legally Advanced Power Conversion Solutions, Inc.) is a U.S.-based designer and manufacturer of high-performance film capacitors serving OEMs, Tier 1 suppliers, and system integrators across electric vehicles, electrified aviation, grid infrastructure, oil and gas, pulsed power, and medical laser markets. The company sells quote-based custom capacitor solutions, standard discrete DC link capacitors (Power Rings) rated 500V to 1800V with capacitance from 120µF to 1600µF, switch-module-specific test kits, universal busbars, and low-cost engineering pre-study services to enterprise customers including Dana TM4, Infineon, Danfoss, Candela Laser, and Cissoid SA.

The company's flagship technology is its proprietary Power Ring annular form factor film capacitor, originally developed under a U.S. Department of Energy SBIR grant and protected by granted U.S. and global patents on both the winding architecture and the surface mounting approach. The annular design minimizes winding height-to-diameter ratio to maximize the end connection area for thermal extraction, delivering ESR at or below 100 micro-Ohms and ESL below 5 nH when integrated with appropriate switch modules. Advanced Conversion pairs this architecture with semi-exclusive inbound licensing of W.L. Gore's self-healing PTFE dielectric film for operation up to 200°C and Peak Nano's NanoPlex LDF film for 800V+ e-mobility and SiC inverter applications.

The company operates a hybrid distribution model combining direct enterprise field sales with four regional distributors covering North America (NAC Semi), Taiwan (Jin Zon), South Korea (Flux Interconnect), and the UK/EU (Pulse Power and Measurement). Manufacturing and engineering are based in Barre, Vermont (headquarters and original production), Loveland, Colorado (AS9100D-certified advanced applications engineering and aerospace production), and Xiamen, China (Asia operations), supported by a global team of 11-50 employees capable of producing over 100,000 film capacitor assemblies per year. Since March 2023, Advanced Conversion has operated as a wholly-owned subsidiary of Electro Technik Industries (ETI), a Clearwater, Florida-based diversified passive electronic components group operating 15 subsidiaries.
