Planar Transformer

As switching frequencies exceed 1MHz, planar transformers enable unprecedented power density with PCB-embedded windings. These flat-profile designs solve thermal and EMI challenges across next-generation power systems.EV Fast Chargers integrate multi-layer constructions achieving 98.2% efficiency at 50kW. Laser-etched windings reduce AC losses by 40% in 800V silicon carbide systems.Data Center AI Accelerators utilize 3D-printed cores supporting 5A/mm² current density. Integrated heat pipes dissipate 250W/in³ in GPU power delivery modules.Medical Implant Chargers adopt biocompatible planar designs with 0.3pF interwinding capacitance. Hermetic sealing enables operation in MRI 7T fringe fields (>10mT).Industrial Drives deploy sandwich structures eliminating proximity effect at 500kHz. Water-cooled variants sustain 25kW/in³ in robotic welding power supplies.Aerospace DC-DC Modules leverage ceramic substrates surviving 20g vibration. Vacuum-compatible units operate at 70km altitude with <0.1% parameter drift.The industry accelerates standardization of thermal derating curves for GaN/SiC applications. IPC-6012 Class 3 criteria now govern high-current PCB transformers.
Next-phase R&D focuses on AI-optimized winding patterns using magnetic field tomography. Cross-industry initiatives develop recyclable ferrite-polymer composite cores.
