The 3-phase half-wave rectifier given in the figure is connected to 3-phase 380 380 V 50 Hz network and feeds 20 Ω ohmic load. Plot the average value of the current flowing through the load and the waveform (vdc) of the voltage across the load on the dashed curves given.

Q.4) A single-phase full-wave controlled rectifier is supplied from 220V, 50Hz. The load is R 100 and L 100mH. Find the firing angle that produced ripple factor equal to 121%. Q theo WILLE K

Question No. 24 A three phase diode bridge rectifier is feeding a constant DC current of 100 A to a highly inductive load. If three-phase, 415 V, 50 Hz AC source is supplying to this bridge rectifier then the rms value of the current in each diode, in ampere, is

THREE PHASECONTROLED RECTIFIER It is used to feed a physical load which is resistance of 6 ohm And inductive impedance high enough for the current to be continuous and free from vibrations and the THREE PHASECONTROLED RECTIFIER is connected to delta and his voltage 100 volt , What is the value of the power drawn from the source if the ignition angle is 45 degrees?
