Understanding the role of inductors in power electronics
The inductor, which stores energy, supplies energy to the circuit to maintain current flow during "off" switching periods, thus enabling topographies where output voltage exceeds input voltage. Due to the way they work — by not only altering electric field but the magnetic field around it — many people struggle to understand them.
Iron Powder Cores for Switchmode Power Supply Inductors
HOME APPLICATION NOTES MICROMETALS, INC • 5615 E. LA PALMA AVENUE •ANAHEIM, CALIFORNIA 92807-2109 •USA 1 Iron Powder Cores for Switchmode Power Supply Inductors by: Jim Cox Purpose: The purpose of this application note is to cover the properties of iron powder as a ...
The Fundamentals of Inductors in AC Circuits
The negative pulses of the power curve do not mean, however, that we have discovered negative power but that we have found energy that has been returned to the circuit. That means the sign of the power waveform reverses every quarter of a cycle, showing that power is alternately fed into and returned from the inductor.
Applications by Frequency
Energy storage inductor designs will be limited by either magnetic saturation or excessive temperature rise resulting from both winding and core losses. In the case of iron powder, due to the fairly low permeability, moderate core loss properties, and very gradual saturation characteristics; designs are almost always limited by temperature rise rather than …
