Q3) A three-phase rectifier has an RL load and is supplied from a Y-connected supply.

1) Draw the equivalent circuit for output voltage harmonics

2) By considering only the first harmonic, i.e., n = 6, determine

a. The expression of the Fourier series for the output voltage.

3)

b. The expression of the rms value of the output current harmonic.

c. The expression of the rms value of the ripple current lac.

Find the expression of the ripple factor RF for the output current

4) If the peak phase voltage is VM = 170 V at 60 Hz and the load resistance is R = 200

2, determine the load inductance L to limit the ripple current to 2% of the average value
