An AC-AC converter with a thyristor connected to a 250 V (phase-neutral) and 50 Hz source is Y-connected. It feeds a 3-phase resistor. Circuit losses are neglected. Load resistance is 10 Ω / phase, α trigger angle is ?/6rad.

Accordingly

a) Calculate the effective values of the output voltage, output current and output power of the converter.

b) Find the total reactive and total harmonic powers for the α angle value you obtained.

c) Calculate the phase shift angle, phase shift factor and power factor of the basic component of the output phase current for α.

Please write all a-b-c answers clearly. Thank You!!
