A single-phase ac voltage regulator has a resistive load of R= 10 W, and the input voltage is Vs = 240 V, 50 Hz. The delay angle of each of the Thyristors is a = p/2. Determine:

(a) The rms value of the output voltage.
(b) The Fourier coefficients of the fundamental, 11th and 13th current harmonics.

 

You might start by drawing the expected load voltage waveform. The load R value will be ohms - rather than watts. The load power dissipation is in watts.
