PLANAR MAGNETICS DESIGN: TWO-DIMENSIONAL WINDING LOSSES CALCULATION
The objective of this App Note is to compare two winding losses calculation models: the classical Dowell one-dimensional (1-D) model and a twodimensional (2-D) model, that takes the edge effect into consideration.
FULL BRIDGE TRANSFORMER DESIGN: KEY ASPECTS
FULL BRIDGE TRANSFORMER DESIGN: KEY ASPECTS
In this app note it will briefly commented some key aspects to take in consideration for the design of the Full Bridge transformer. It will consider a secondary side with center tap, but it can be considered for a single secondary winding.

HYSTERESIS LOSSES: LOSSES IN THE CORE THAT RESULT IN AN INCREASE OF TEMPERATURE
In this App Note hysteresis losses will be discussed.
INDUCTOR SIZE REDUCTION, DECREASING THE VOLTS PER SECONDS APPLIED
INDUCTOR SIZE REDUCTION, DECREASING THE VOLTS PER SECONDS APPLIED
In this application note it is presented one strategy to reduce the size of magnetics, based on synchronizing both power stages, a voltage fed topology in cascade with a current fed circuit.
FILTER DESIGN FOR GRID CONNECTED SYSTEMS
FILTER DESIGN FOR GRID CONNECTED SYSTEMS
The objective of this App Note is to show how to design a filter for gridconnected inverters that are widely used in solar and wind generation plants. Namely, various topologies, and strategies to optimize the size, stability and the efficiency of the system will be covered.
LAMINATED CORES: A QUICK INTRODUCTION TO DESIGN
LAMINATED CORES: A QUICK INTRODUCTION TO DESIGN
The objective of this app note​ is to introduce laminated cores, explaining why they are used instead of solid cores when eddy currents must be low and some of the difficulties that magnetic designers can find when this core construction is needed.
LOSSES DUE TO FRINGING FLUX: ESTIMATION, TESTING AND AVOIDANCE
LOSSES DUE TO FRINGING FLUX: ESTIMATION, TESTING AND AVOIDANCE
​The fringing flux is an effect appearing in gapped magnetic, where the magnetic flux lines bulge outward due to mutual repulsion. This is translated into a modification of the inductance and a possible overheating in the wires surrounding the gap.
