Extracted text: a) Figure Al shows the output voltage and output current for a single phase rectifier. The average voltage output, Vo(avg) for this rectifier is 67.8V. Given that the firing angle a= and the extension angle ß = 240°. If the total impedance Z=502, calculate the input voltage, Vs and the average output current lo(avg)- Rajah Al menunjukkan voltan keluaran dan arus keluaran untuk sebuah penerus fasa tunggal. Voltan purata keluaran Vo(av9) untuk penerus ini ialah 67.8V. Sudut picuan a=r/6 dan sudut sambungan ß=240°. Sekiranya jumlah galangan ,Z=50Q, kira voltan input, Vs dan purata arus keluaran, Io(avg)- we Figure Al Rajah Al
