1000 A High‑Current Planar Transformer with Zero Compromise
For designs requiring massive current delivery at high switching frequencies, precision in conductor layout, parasitic management, and heat flow is essential. This custom Payton Planar Magnetics transformer demonstrates how far planar technology can extend, supporting 1000 W continuous power in a remarkably small package.
The unit operates in full‑bridge topologies at 400 kHz, with outputs of 12 V at 83 A or 0.8 V at 1000 A for ultra‑high current needs. Input flexibility includes 40-60 V ranges, or alternative configurations handling 400 V down to 48 V, 12 V, or 0.8 V at 1000 A in one stage.
Performance and Compact Design Highlights
Achieving 99.15% efficiency with minimal losses, the transformer measures just 30 × 26 × 15 mm and is conduction‑cooled for use in sealed or harsh environments. It maintains only a 40°C temperature rise at full load, proving reliable under sustained high‑stress conditions.
Compatible with all SMPS topologies up to 5 MHz, it excels where precise control of parasitics, material choices, and manufacturing repeatability are non‑negotiable, such as EV fast chargers, data center PSUs, medical devices, and industrial equipment.
