This course is a complete AC analysis course. It starts with very simple math knowledge of sinusoids and phasors.(tools we use during analysis)1- ) Sinusoids and PhasorsIn this unit, students will gain the mathematical knowledge needed before diving into analysis. The topics are as follow ;IntroductionSinusoidsPhasorsPhasor Relationships with Circuit ElementsImpedance and AdmittanceKirchoff's Laws for Frequency DomainImpedance Combinations2- ) Sinusoidal Steady State AnalysisIn this unit, students will practice basic AC circuit analysis by using the same methods for DC. Students will see that the methods are both applicable to AC and DC.The topics are as follows ;Nodal AnalysisMesh AnalysisSuperpositionSource TransformationThevenin and Norton TheoremOp Amp AC Analysis3-) AC Power AnalysisIn this unit, student will know how to measure AC power in AC circuits which is a different process than the usual DC way.The topics are as follows ;· Instantaneous and Average Power· Maximum Average Power Transfer· Effective or RMS value· Appearent Power and Power Factor· Complex Power· Conservation of AC Power· Power Factor Correction4-) Three Phase CircuitsIn this unit, student will learn how 3-Phase Circuits work and why they are more efficient than a single phase circuit.The topics are as follows ;· Balanced Three Phase Circuits· Balanced Y-Y Connection· Balanced Y-D Connection· Balanced D-D Connection· Balanced D-Y Connection· Power in Balanced Three-Phase Circuits· Unbalanced Three-Phase Circuits5-) Magnetically Coupled CircuitsIn this unit, students will learn that a circuit is not only conductively coupled but also magnetically. Key element in Magnetic Circuits is "inductor".The topics are as follows ;· Mutual Inductance· Energy in a Coupled Circuit· Linear Transformers· Ideal Transformers· Ideal Auto-transforemers6-) Frequency ResponseIn this unit, student will understand; time is not the only variable in our circuits. Frequency plays a vital role in circuit analysis and will be really helpful for the rest of one's journey.The topics are as follows ;· Transfer Function· Decibel Scale· Bode Plots· Series Resonance· Parallel Resonance· Passive Filters· Active Filters
