  Utility companies generate three phase electric power, which consists of three sinusoidal voltages with phase angles of 0, 120, and 240 degrees., The AC generators described in most introductory textbooks are single phase generators, so physics students are not likely to learn much about three phase power.

  Three-phase circuits, in the majority of cases, are symmetrical. They consist of three identical branches, each of which has the same impedance. Each of these branches can be treated exactly like a single-phase circuit. Consequently, three-phase circuits are not necessarily harder to work with than single-phase …

  (i) Explain the working of single phase ac voltage regulator working on-off control mode. Derive the expression for rms value of load voltage.(8) (ii) A single phase ac voltage controller with resistive load of R=10 Ω and the input voltage is Vs=120V, 60 Hz. The delay angle of thyristor T1 is α =π/2.

  To improve the input power factor of the ac chopper the asymmetrical PWM control techniques have been proposed [3]. A new asymmetrical PWM technique for single phase ac choppers, which improves the input power factor and eliminates the harmonics of load voltage is introduced [4], but harmonic content of the input current is high.

  AC circuit elements consist of resistors (R), inductors (L) and capacitors(C) which can be fed from either a 3 phase or 1 phase 60 Hz, 120V source. Resistor and inductor combination connected to a single phase AC source results in a lagging current with respect to voltage.

  The simulation results proved good performance of the ac single phase choppers with IGBT’s an high chopper frequency. A sinusoidal input current was obtained by using the power circuit with filter in figure3. In this case the phase shifting angle of the fundamental input current is reasonable. This phase shifting angle varies with duty factor D.
