Q1. A three-phase, fully-controlled bridge rectifier is connected to a 400 V line-to-line, 50 Hz AC supply. assume that an active load capable of delivering real power is connected at the converter output, drawing a level load current of 40 A, with a firing delay angle a = 150°. Neglecting the device voltage drops, Determine the mean value of converter output voltage. What is the operating mode of the converter ? b. Plot the load voltage and supply current waveform i, on the graph given below. Indicate the x- and y-axes scales on the waveforms. Use a computer simulation program here. a. 本r Load VL T. T Q1.
