QUESTION 3 (25 marks) (b) Ide (c) -Ide (d) 0 If ripple-free load current in steady-state is assumed, the input current i, waveform of the single-phase full-wave rectifier may then be depicted as shown in the figure above for an ideal input transformer. With the assumption that the supply is ideal and perfectly smooth and ripple free load current, which implies an infinitely large load inductance, it is quite straightforward to obtain an analytical expression for the input current harmonics. The rectangular wave is defined as f(x)= By using the full range Fourier Series, compute the (a) Fourier coefficient, a Fourier coefficient, a first 2 harmonics of b 7 Fourier series expression of I when 0<x<T when <a <2m 2x cot 4 (4 marks) (6 marks) (13 marks) (2 marks)
