Planar PCB Winding High Frequency Power Transformer 1kW

Engineered for the next generation of high-density server power supplies and telecom rectifiers, our planar high frequency transformer employs multilayer PCB technology to replace traditional wire-wound construction. This approach delivers exceptional parasitic parameter consistency from unit to unit, making it ideal for LLC resonant converters and phase-shifted full-bridge topologies at power levels up to 1kW.

Key Features

  • Ultra-Low Profile: Total height under 15mm, enabling slim 1U and blade server power supply form factors that are impossible with conventional wound transformers.
  • PCB Winding Technology: Photo-etched copper traces on multilayer FR-4 or high-Tg substrates provide precise, repeatable winding geometries with tight coupling and predictable leakage inductance.
  • Superior Thermal Management: Large flat surface area of planar construction facilitates direct heatsink attachment, reducing hot-spot temperatures by 15-20°C versus equivalent wound designs.
  • Wide Frequency Range: Optimized for 100kHz-1MHz operation using advanced low-loss ferrite core materials (3F36/3C96 equivalents).
  • High Efficiency: Achieves ≥97% conversion efficiency when paired with modern GaN or SiC switching devices in LLC resonant topologies.

Applications

  • Server and Data Center Power Supplies (1U/2U)
  • Telecom Rectifier Modules (48V bus)
  • EV On-Board Chargers (OBC)
  • High-Power LED Driver Systems
  • Industrial Welding Power Sources
  • Renewable Energy Micro-Inverters

Why Planar?

Planar transformers eliminate the variability inherent in hand-wound or semi-automated winding processes. Every unit has identical AC resistance, leakage inductance, and interwinding capacitance — critical for mass-produced resonant converters where parametric variation directly impacts efficiency and EMI compliance.

Engineering Support

Our team provides full design support including magnetics simulation (ANSYS Maxwell / PExprt), PCB layout review, and thermal analysis. We can integrate directly with your PCB design files to create the optimal transformer solution for your specific topology and power requirements.
