Step 1

Sketching the waveforms: - Vo (output voltage) will be a half-wave rectified sine wave, starting at the firing angle α and ending at π (180 degrees). - IL (load current) will follow the same pattern as Vo, since IL = Vo/R. - IT1 (current through T1) will be Show more…

Half-wave single-phase controlled rectifier with resistive load. It has a load of R = 15Ω and Vs = 220 sin (314t) and unity transformer ratio. If it is required to obtain an average output voltage of 70% of the maximum possible output voltage, * Sketch the waveforms for Vo, load current IL, the current through T1 (IT1), VAKT1 voltage across T1. * Calculate: - (a) The firing angle, α, - (b) The efficiency, - (c) Ripple factor, - (d) Transformer utilization factor, - (e) Peak inverse voltage (PIV) of the thyristor, and - (f) The crest factor of input current.
