2. A 3-phase full-wave bridge rectifier is built using six power diodes numbered 1 to 6. The phase sequence of the 3-phase source is ABC and the line to line voltage is 191 V. The line to neutral voltage of phase A has an angle of -30 degrees. The anodes of the diodes 1, 2, 3 are connected to phase A, B, and C, respectively, and the cathodes of diodes 1, 2, and 3 are connected to a common terminal that serves as the positive terminal of the rectifier's output. The cathodes of diodes 4, 5, and 6 are connected to phase A, B, and C, respectively, and the anodes of diodes 4, 5, and 6 are connected to a common terminal that serves as the negative terminal of the rectifier's output. If diodes 1 and 3 are damaged and act as an open circuit, what would the DC voltage be at the load? 3-phase-demos-3vi File Edit View Project Operate Tools Window Help Waveform Chart 8 21 2- 18- 16- 14- 12- 1- 08- 06 04- 02- 0 -02- 04- -06- 08- -1- -12- 14- Time རྔ་ལྷ་ལྟ་ Amplitude Time A-B (D1, DS) A-C (D1, D6) B-C (D2, D6) B-A (D2, D4) C-A (D3 D4) C-B (D3, D5) A-B A-CA B-C B-A C-A C-B KKKKKK 081 -0.92 -1.73 081 0.92 1.73
