Custom magnetics for automotive systems and infrastructure
Automotive and EV applications push magnetics into some of their harshest operating conditions — wide temperature ranges, vibration, continuous duty cycles, and increasingly stringent efficiency standards. For over 60 years, Pacific Transformer has built custom transformers, inductors, and chokes for automotive electronics, EV charging infrastructure, recreational vehicles, and the control systems that run them. We're FMEA approved and have a proven track record supplying into automotive-adjacent programs at GM and International Rectifier.
Built for the Demands of Modern Mobility
Automotive and EV magnetics don't get the luxury of a controlled environment. They have to perform across extreme temperature swings, survive constant vibration, and meet efficiency targets that tighten with every product generation. Our engineers design custom power transformers, flyback transformers, gate drive transformers, and high-frequency inductors for EV charging systems, onboard power conversion, motor control, and auxiliary electronics — built to your electrical specs and mechanical constraints from the start.
As the automotive industry shifts toward electrification, the magnetics inside charging infrastructure, battery management systems, and onboard converters have become increasingly critical. We've been designing for high-frequency switching and power conversion long before EVs were mainstream — and we're ready to apply that experience to whatever you're building next.
Experience in Automotive & Recreational Vehicles
From EV charging stations to recreational vehicle power systems, Pacific Transformer has built custom magnetics across the full spectrum of automotive and mobility applications. Our FMEA approval by GM and International Rectifier reflects the rigor we bring to automotive supply chain requirements. We understand the documentation, traceability, and quality standards that automotive programs demand — and we build our processes around them, not around them as an afterthought.
