solve the question and demonstrate alor please I want to understand prefectly. Thank you.

Q1. a) An SCR based AC power controller circuit is given in Figure 1. The circuit connects a 240V 50Hz AC source vi to a resistive load with resistance of 100. If the delay angle is a-15°, draw the waveforms of the load voltage Vo, and the voltage across SCR2. Calculate the power supplied to the load. + Vi Va + 2 SCR2 H₁₁ SCR₁ Figure 1 SCR based AC power control circuit Va + 2 io b) Figure 2 is a single phase 2-level voltage source converter (VSC) with a DC voltage Vd-200V. A PWM scheme, by comparing a reference value with a 10kHz triangle waveform, is used to control the switches S₁ and S2. The modulation index of the PWM is m=0.8. With the aid of graphs explain how pulse signals for the switches are generated, sketch the output voltage Vo, determine the duty cycle, and calculate the average output voltage. + Vo + Vo √ ₂ == Figure 2 A single phase VSC

Find voltage regulation in typing format please ASAP for the like

I need a diagram of a circuit by the transform and rectification block, using the bridge rectifier circuit (2W10). It can be a source of any value. You don't need to do any calculations, just a drawing of how this circuit will look, please.

hello, am doing past years, but need 3rd party confirmation on answers, I tried checking with my friend but they and I have different answers. If possible please include a bit of explanation as I am afraid that my grasp on the concepts are not firm

Three phase Bridge rectifier operated from a 380V, 50Hz source throughout three-phase Y/Y connected transformer with ration 2:1. The load current has continuous character with negligible ripples and average thyristor current of 15A. The circuit inductance per phase is 1.2mH. The rectified voltage due to overlapping angle is 90 % of that voltage when this angle is neglected. 1- How much will the voltage drop be due to circuit inductance * 2- How much will the dc average voltage Vdc(alpha) be. 3- How much will the firing angle be ? 4- The overlapping angle. 5- How much is the percentage change of the output dc power if the thyristors T2, T4 and T6 are replaced by three diodes D2, D4, D6. 6- How much will be the maximum RMS phase current for the mentioned in previous task circuit ( semi-converter). 7- If an additional of 1 mH inductances are added to the existing inductances in the phases , how much will the overlapping angle be. The dc load current is kept constant & the…
