About ICD&C

Design office and sales.

We’re a team of design engineers building inductive components — transformers and reactors, conventional and planar — for clients running industrial and institutional infrastructure projects.

Every project gets full technical support from spec to delivery, with our own engineers staying close to your electronics team throughout — not a handoff to a black box overseas.

  • Design of inductive components and production specs for HF/LF transformers and reactors, per IEC/UL.
  • Project and production management aligned to IEC, UL and ETL standards.
  • Electronics design collaboration and European production.
  • Project management run jointly with the client, end to end.
  • Production and sourcing management through China manufacturing partners.

Custom design

Not on the list? We’ll design it.

Standard catalog types cover most jobs, but a lot of our work starts from a blank spec sheet — a voltage, frequency or footprint the catalog doesn’t have. Our engineers take it from there: core selection, winding layout, insulation class and mechanical mounting, built around your application rather than a datasheet.

Spec review

Voltage, frequency, power, mounting and target standard.

Design

Core, winding and insulation chosen for the application, not a template.

Prototype and test

Verified against IEC/UL before production is approved.

Production

Run through our Europe and China manufacturing partners.

Every custom design goes through the same IEC/UL verification as our standard range, with a prototype signed off before production starts.

Experienced designer with a demonstrated history of working in the electrical and electronic manufacturing industry. I lead the design and delivery of inductive components, obtain UL/IEC approvals, and ensure compliance with ISO 9001 standards — working closely with customers on their specific needs.

I have fostered collaborations with customers in multiple electrotechnical sectors, enhancing their experience and satisfaction. I have also overseen quality management processes, conducted external audits, and ensured operational excellence in global companies.

As Transformer Lead Engineer at a Danish global energy company, I managed the transformer room for the V164 wind turbine type in Århus. I worked with suppliers on transformer product development for new turbine versions, addressing concessions and deficiencies and supporting subject matter experts in high-voltage equipment, with a focus on reliable transformer operation and turbine performance.

As a member of the International Electrotechnical Commission TC96 Transformer Committee, I work on the publications under TC 96’s responsibility and on revising IEC 60989 for inclusion in the IEC 61558 series.

Over the last 40 years I have designed inductive components for high- and low-frequency applications across many industrial sectors, for both small and high-volume production. I have also evaluated alternative components for a 7 MVA converter and designed control panel systems, with a focus on simplifying complex solutions — working with cross-functional teams to deliver cost-effective results without compromising quality.
