1. A 50 Hz 3-phase Have wave uncontrolled rectifier circuit is used to supply a resistive load of 100 ohms. The supply is unbalanced and defined as v.-127.28 cos (ot) V 127.28 sin (ot-0.5236) V n63.64 cos (ot+2.0944) V a) Draw the circuit diagram. b) Draw the three phase voltages wave forms. c) Use phasor diagram or any other method to obtain the line voltages v and d) Draw the line voltages v and v wave forms. e) Derive an expression for the output voltage v f) Determine the conduction period for each diode g) Draw the output current i, wave form. h) Calculate the average value of the output voltage i) Draw the waveforms of one of the supply currents, the output voltage, and the anode to cathode voltage of one of the diodes.
