Course Outline

? Prerequisite: ECE 202 ? Circuits II

? Operational amplifiers, average, complex, imaginary and real power; effective values of voltage and currents, three phase circuits, delta and wye connections. Complex frequency; sinusoidal forcing functions and natural response. Resonance: general case, special cases in series and parallel circuits. Scaling: magnitude and frequency. Mutual inductance, transformers as circuit elements; linear and ideal transformers. Admittance, impedance and hybrid parameters. Trigonometric and complex Fourier series.

? Course Objective: Upon completion of this course, every student should have gained

1. a broad familiarity with the fundamental principles of basic electric energy system components.

2. an understanding of the equipment needed for generation and delivery of bulk electric energy and basic steady-state analysis methods for power systems.
