A fully controlled, single-phase bridge rectifier is powered from an ideal 220V, 50Hz source. The rectifier is triggered with a trigger angle of 60 degrees and provides a smooth current of 50A to the load at the output. According to this: a) Draw the waveform of the output voltage in scale and calculate the average value of the output voltage. Combine the average voltage signal with the output voltage wave signal. Show on the same figure. b) Draw the waveforms of the thyristor currents, the gap diode current and the current drawn from the source in scale. c) Calculate the value of the filter inductance used at the output when the ripple in the load current is 3A. (Do the operations by showing the output voltage shapes and areas on the figure. The answers should be in the system and order in the solved examples.)
