Basic EMI Concepts

 

Understanding EMC is all about two important concepts: (1) all currents flow in loops and (2) high frequency signals are propagated as electromagnetic waves in transmission lines and the field energy travels through the dielectric. The two concepts are related because they are intertwined together. Digital signals create the propagating field, which induces the convection … [Read more...]

Oh How I Hate to Commutate!

 

My favorite Sophomore in Engineering, Roger, and his group, made a small crane for their engineering project. It had many EMC issues.  One issue they had was noise from permanent magnet DC motors.  I am so glad Roger cares about this issue, because I have modeled a few permanent magnet DC motors, and I can explain how to design it so that then so they are … [Read more...]
