APPLICATIONS

Applications

Selection starts from the operating point: switching frequency, DC bias, thermal conditions and isolation spacing together determine grade, geometry and gap.

Applications / Engineering

Four system types and the parameters that decide the core

From high-current power delivery to industrial conversion, every application draws a different design boundary. DC bias, loss, insulation and temperature rise decide which core or inductor fits.

DC-DC / VRM / POL

High-current DC-DCinductance under DC bias

Load current, available height and DC bias decide how a powder core or a molded inductor actually performs.

SMPS and LLCcore loss and winding window

Switching frequency, flux swing and winding window together decide the ferrite grade and the geometry.

EV chargingcreepage and clearance

Magnetic design for PFC and the isolation stage has to consider winding window, creepage and clearance together.

Industrial and storagetemperature rise and overload

Thermal rise, load cycling and fault conditions decide the material choice and how much saturation margin to keep.

Magnetics inside typical power systems

Each system below stresses the magnetics differently: current magnitude, switching frequency, thermal cycling and available space. These are the power stages we can supply for; grade and values are confirmed per project.

AI / GPU power delivery

GPU VRM stages need inductance that stays usable through fast current steps. Inductance versus DC bias, AC loss and temperature rise are confirmed per part number against the switching frequency and current profile of the actual design.

Solar inverter

Low-loss magnetic components for string and central inverters. Where high DC bias makes a gapped ferrite impractical, a powder core can be evaluated; core volume and loss should be compared under identical operating conditions.
