Buck-Boost Converters
A buck-boost converter is used to convert a switched DC voltage of some value to another DC voltage of some fixed value. They are primarily used in...
Inductors
WHAT IS INDUCTANCE and INDUCTORS? “Inductance is the property of an electrical conductor by which a change in current through it induces an...
IMPEDANCE AND AUDIO TRANSFORMER DESIGN
One of the most “mysterious” transformers to design are impedance and/or audio transformers. From here out I’ll refer to both types just as...
Magnetic Designs
When a voltage is applied to a finite inductance for some period of time it gives rise to a current though some number of turns…..the applied...
Minimizing Power Loss in a Transformer
You have a set of requirements …. you have a needed output power which is some output current at some voltage. Your input voltage is known as is the...
Using Faraday’s Law of Induction
The intent of this write-up is to provide engineers with an understanding of how a few of their most useful equations are derived. Most engineers...
Avoiding Core Saturation
Lines of magnetic flux are created when a current flows through a conductor. They can transport energy from one winding to another usually though a...
