The distribution parameters for magnetic components should be used by specialists in switching power supplies.

Importance of magnetic components in power converters

Design Considerations and Appropriate Models for Magnetic Components

Influence of magnetic component model parameters on circuit characteristics

Eddy current (field) characteristics of a transformer - effect of losses

Magnetic (field) characteristics of transformers - inductive action

Electrical (field) characteristics of transformers - capacitive action

Function: plays role of transferring and storing magnetic energy, which is an important component

Features: large volume, large weight, large loss, strong impact on circuit performance

Problem: Strongly affects power density of converter and becomes a bottleneck in development

Topologies: direct, flyback, push-pull, full bridge phase shift, LLC, etc., magnetic integration, magnetic coupling;

Control: control chip control circuit, transformer filter line;

Packaging: PCB winding, synchronous MOS winding, ultra-thin magnetic components;

Components: active devices, capacitors, magnetic components (custom design);

Simulation: circuit model, device model (IC, MOS, diode, capacitor, magnetic components);

EMC: layout, EMI filter, distributed parameters, near field communication;

Production: automation, magnetic components (handmade)

Quality: testing of magnetic components, failure analysis.

Magnetic component technology is very important for power converters;

The distribution parameters of magnetic components have an important influence on characteristics of circuit (efficiency, power density and reliability);

From level of magnetic field, electric field and eddy current field inside magnetic component, one can more deeply and fully understand parameters of magnetic component.
