| Abstract |
Magnetics are historically one of the physically largest components in power distribution networksfrom milliwatts to megawatts. Consistent with the overall goal to reduce the visual presence of power converters that are necessary for continually advancing electronic devices, there is a continual push from the smallest to the largest power converters to have the magnetics blend in with other components of power delivery systems relative to their physical appearance, physical size, and cost. Power distribution systems will always require the magnetics function and accordingly the magnetics function will not disappear. This drives the term 'make magnetics invisible' or more realistically become indistinguishable from other components of the overall product assembly. The reality is thatmagnetics become less visible by moving towards more complete integration with the semiconductor devices at the Integrated Voltage Regulator (IVR) levels or by physical size reduction at the Solid-State Transformer (SST) levels. Integration and miniaturization are the main objectives for power magnetics across all power levels. |
