Transformers/Inductances Details TRIZ Cases
- Grain-Oriented Electrical Steel Groove Control for Lower Iron Loss
Controlled groove formation and SiO2/FexSiOy oxide balance help grain-oriented electrical steel cut iron loss while maintaining flux density.
- Sealed On-Load Tap Changer Switch Housing for Arc Containment
A hermetically sealed switch housing uses vacuum or arc suppression gas to contain arcing and contamination in on-load tap changers.
- Magnetic Particle Coating for Permeable, High-Resistance Cores
A dual-alkoxide coating film prevents particle adhesion and fracture during molding, raising core permeability and specific resistance.
- Spiral Coil Surface Roughening to Limit DC Resistance Rise
Selective roughening of upper spiral-pattern regions improves resin adhesion while limiting sectional-area loss and DC resistance rise.
- Rotatable Flange High-Voltage Feed-Through for Easier Bushing Mounting
A rotatable flange lets heavy high-voltage bushings align and fasten more easily, reducing installation effort while keeping secure sealing and insulation.
- Inductor Core Surface Structure for Electronic Pen Coil Stability
A tapered inductor core with lower front-side surface skewness and a flange increases coil friction to prevent displacement in electronic pens.
- Solenoid Bobbin Opening Geometry for Stable Wire Winding
Tapered bobbin wall regions and guide elements reduce wire winding offset while preserving larger openings for coolant and oil exchange.
- Bi-Layer Superconducting Ground Plane for Tunable Inductance
A bi-layer superconducting ground plane tunes planar inductance via bias current while preserving supercurrent capacity and noise tolerance.
- Recessed Core Piece Structure for Coil Insulation Protection
A recessed gate-mark structure traps detached soft magnetic particles before they reach the coil, protecting insulation and easing reactor manufacturing.
- Ultra-Thin Power Inductor Casting to Protect Coil Integrity
Integral pouring with warm-water pressing enables ultra-thin power inductors while avoiding coil damage, short circuits, and dry-press limits.
- Magnetic Composition Binder for High-Temperature Reliability
Restricted-rotation bisphenol epoxy binds magnetic particles to resist thermal degradation and preserve reliability in high-temperature use.
- Passive Electronic Structure With Buffer Layer Against Passivation Cracks
A high-strength buffer layer at metal edges absorbs thermal expansion stress, preventing passivation cracks and delamination during thermal cycling.
- Wound Core Corner Geometry for Lower Iron Loss
Controlling wound core corner angle to 23°-50° confines magnetic flux and cuts strain-induced iron loss without annealing.
- Grain-Oriented Electrical Steel Strain Pattern for Lower Iron Loss
Periodic width-shifted linear strains refine magnetic domains to cut eddy-current loss while suppressing hysteresis loss and noise.
