A single-phase thyristor-controlled rectifier supplies the lighting in a theater. The light control requires the reduction of the average dc voltage to 70% of the rated voltage when the lights are dimmed. Calculate the required delay angle. The 60 Hz ac input is 220 V, and the dc output rating is 120 V. The lights normally draw 2 kW at the rated conditions.
