Reconsider Problem 3.29. If Va,VbandVc are a negative-sequence set, how would the voltage and current relationships change? (a) If C1 is the complex positive-sequence voltage gain in Problem 3.29 and (b) if C2 is the negative sequence complex voltage gain, express the relationship between C1andC2

I need the correct expert solution with explanation of the steps of the solution and the abbreviations, please.

Q-2 A Cockcroft-Walton type voltage multiplier has Seven stages with capacitances, all equal to 0.3 µF. The supply transformer secondary voltage is 150 kV at a frequency of 100 Hz. If the load current to be supplied is 3 mA, find (a) the percentage ripple, (b) the regulation, and (c) the optimum number of stages for minimum regulation or voltage drop (d) the maximum output voltage.
