High-current DC, pulsed power and magnet systems for industrial processes and test facilities.

Industry

Power and magnet systems built for production duty

Woodruff Engineering supplies high-current DC power supplies, pulsed power systems and custom electromagnets for industrial processes, test facilities and production lines. The same engineering that goes into our fusion and national-laboratory systems — precise regulation, robust protection and water-cooled power electronics — is packaged for continuous industrial operation.

We work with process engineers and facility teams from specification through factory acceptance testing, and design every system to integrate with existing SCADA and PLC-controlled lines.

Applications

Where our systems are used

Electrochemical processing

Electroplating, electrolysis, hydrogen production and cathodic protection need stable, high-current DC. Our 5 kA / 60 V supply holds ripple below 0.1% across the full load range.

High-power DC and rectification

Modular, water-cooled three-phase rectifiers convert 480 VAC mains to regulated DC at 1.6 MW per module, with IGBT/SiC regulation and Ethernet control, scaling to multi-megawatt systems.

Electromagnetic forming and pulse welding

Capacitor banks and pulsed power supplies for magnetic pulse forming, welding and crimping, with modular architectures that map onto industrial duty cycles.

Impulse magnetizing and pulsed magnets

Pulsed supplies with programmable ramp, flat-top and decay profiles, I²t protection and optional energy recovery for repetitive megawatt pulses.

Thermal and component testing

Precisely regulated high-current supplies for thermal cycling, conductor and busbar testing, and qualification of power components.

Non-destructive testing and industrial magnets

Custom electromagnets, EMAT coils and large field systems for non-destructive testing, materials processing and magnetic test fixtures.

Built for industrial duty

Reliable, controllable, serviceable

Quality & compliance

Certified quality, controlled exports

Our customers include national laboratories, defense primes, fusion developers and universities around the world. They need to know that what we ship meets specification, and that it reaches them lawfully. Both are built into how we run every job.

ISO 9001:2015 certified

Woodruff Engineering operates a quality management system certified to ISO 9001:2015. It covers the design, manufacture and test of our magnets, power supplies and pulsed power systems.

Every order follows a documented product-realization process, from contract review through design, build, test and delivery
Customer requirements are reviewed and agreed before work starts, and design changes are controlled
Design reviews with the customer at concept and final design stages for custom systems
Materials and components bought from qualified suppliers and traceable to each build
Factory acceptance testing before every shipment, with as-built data and test records
Nonconformances recorded and closed out with corrective action
Internal audits and management review drive continual improvement

Our ISO 9001 certificate is available on request.

Export control compliance

High-voltage capacitor banks, pulsed power switches, power supplies and high-field magnets can be subject to US export controls. We manage compliance on every order, domestic and international.

Products and designs classified under the Export Administration Regulations (EAR) and the International Traffic in Arms Regulations (ITAR) before quotation and again before shipment
Customers, end users and intermediaries screened against the US Consolidated Screening List and OFAC sanctions lists
Signed end-use and end-user statements requested for international orders where required
Where a license is needed we tell you at quotation, apply for it, and build the time into the schedule
Controlled technical data and drawings handled under the same rules, with access limited to authorized U.S. persons where required
Export records kept for at least five years
