Question: 2 suppose we want to design a de power supply...

Question details

2. Suppose we want to design a de power supply by filtering the output, Vrec(), of a full-wave rectifier through the following low-pass filter Choke-Input Filter Pulsating DC From Rectifier Fitered DC Output To Load Assume that the trigonometric Fourier series expansion of Vree(t) is given by: 2v2 + Ση.lan cos(n20Ort), where a.- t(1-4n2) a) From known properties of linear systems, write down an expression for the steady state output of the filter b) What are the amplitudes of the de component and the dominant (largest) ac component of the filter output? c) Assuming RL-15 Ω, L-5 mH, choose a value of C such that the amplitude of the dominant ac component of the filter output is (1/25) times the dc component of the filter output. Hint: First find the transfer function, H(s), of the filter and then find its steady state response due to Vree(t).]
