The input voltage to the single-phase cycloconverter of Fig.7.1 is 220V, 50 Hz. The load resistance and inductance are 35 2 and 150 mH respectively. The frequency of the output voltage is 30 Hz. If the converter is to operate with up 75", (a) Sketch approximately to scale, the input supply voltages and the output voltage waveforms. (b) Determine the rms value of the output voltage. (c) Determine the rms value of the load current. (d) Determine the input power factor.
