Passive AC Circuits

AC Circuits and Power Applications is an introductory engineering technology text covering single and three-phase alternating current (AC) power sources, components, connections and loads. Topical coverage includes introductory sinusoidal voltage and phase angle considerations; vector representation of alternating voltages; resistance, reactance, impedance and phase angle determination; single and polyphase transformer operation; polyphase power distribution; common residential and industrial load determination; Wye and Delta transformer connections; power transfer, power factor and power factor correction; balanced and unbalanced resistive and reactive load computations. Diodes, rectifier circuits, AC induction motors and variable frequency drive (VFD) control of induction motors are also investigated. An understanding of direct current (DC) electrical/electronic circuit theory and right-angle trigonometry is strongly suggested.
