Extracted text: AC-AC Converters a) Fig. 1 shows phase-controlled AC-AC converter. Explain the operating principle of AC-AC converter. b) T1 with T2 in the below circuit, find the rms output voltage, the input power factor pf, and the average input current. When the area under the curve of thyristor current is 1.00079 as shown in Fig. 2, vs = 120 V, f = 60 Hz, and R = 10 0. Vrn - T1 igi io. R Vo Fig. 1. AC-AC controller.
