For a single-phase single-pulse thyristor rectifier with resistive load (R=15 Ohms) shown in Fig. 3.1, fed from an AC source with the voltage v,(t) = 220 · sin(314·t). Gate signal Single-pulse Thyristor Rectifier Rload vs(t)=220'sin(314t) a) Replace the single-pulse thyristor rectifier with a full-bridge thyristor rectifier and calculate the efficiency of rectification for this case/topology in the same conditions. b) Replacing the resistive load with a DC motor represented by an equivalent circuit (Fig. 3.2) and considering the load current constant and ripple-free, draw the output voltage and the input current (Is), indicating in the sketch when the thyristors are in conduction.
