Non-linear alternating current circuits

Specialist area:Electrical engineering
Application:Temperature-dependent resistors, three-phase generators, battery chargers

Lecturer:Prof. Dr.-Ing. Hans-Peter Beck
Keywords:Definition and examples:
Linear and non-linear network components, non-linear distortions, rms values, fundamental and harmonic content, distortion power at sinusoidal mains voltage, total power factor, power variables at non-sinusoidal mains voltage

AC circuits with an iron inductor:
Origin of non-linear distortion, fundamental active and reactive power, equivalent-circuit diagram, eddy currents in the iron core, eddy-current and iron losses

AC circuits at higher frequencies:
Origin of the skin effect, penetration depth, frequency-dependent “ohmic” resistances
