Transformers/Inductances Details TRIZ Cases
- Modular Current Sensor Coil Assembly for Large Openings
Segmented sensor modules with locating pins cut substrate waste and cost while preserving accurate current sensing around large conductor openings.
- Si-B Oxide Insulating Film for High-Frequency Dust Cores
A Si-B complex oxide insulating film lowers relative permittivity while preserving initial permeability in soft magnetic dust cores.
- Grain-Oriented Electrical Steel Sheet Grooves for Lower Iron Loss
Controlled groove formation and Fe-O oxide removal cut iron loss while preserving magnetic flux density and coating contact at high temperature.
- Laminated Core Bonding Pattern for Accuracy and Low Stray Current
Selective fastening and adhesion in laminated electrical steel sheets improve dimensional accuracy, magnetic properties, and noise control.
- Ultrathin Power Inductor Casting to Prevent Coil Damage
Integral slurry pouring, warm-water pressing, and curing avoid coil deformation and insulation damage in ultrathin power inductor production.
- Composite Insulating Bushing Structure for Waterproof Busbar Protection
A polyester-glass insulating bushing with silicone sealing improves busbar waterproofing, flame retardancy, and outdoor durability.
- Ferrite Core Composition for Heat-Resistant Wire-Wound Coils
A Cu-Ni-Zn ferrite with trace B and Nb improves thermal shock strength, permeability, and Curie temperature in wire-wound coil cores.
- Transformer Insulator Cover for Wildlife and Debris Short-Circuit Prevention
A non-conductive transformer cover blocks wildlife and debris contact with grounded surfaces, reducing weather-driven short circuits and maintenance.
- Laminated Magnetic Core Structure for High-Current Residual Sensing
An irregular laminated core overlap reduces local saturation, improving small residual current sensing under high primary currents.
- Inductive Coupler Substrate for Transmit-Receive Isolation
A grounded second inductor induces a counter-signal that suppresses filter leakage and improves transmit-receive isolation.
- Coil Conductor Photopatterning for Flat Multilayer Coil Surfaces
Sequential photopatterning of different coil conductors keeps the forming surface flat, cuts process steps, and helps prevent deformation and shorts.
