Given the vectors $v_1 = (0, 1, 0, 2)$, $v_2 = (2, 0, -1, 0)$, $v_3 = (2, -1, 3, 2)$ and $u = (1, -1, 0, 1)$,\Use the Gram-Schmidt process to find an orthogonal basis for the subspace $W$ spanned by $v_1$, $v_2$ and $v_3$. \Find $Proj_wu$, the projection of $u$ onto the subspace $W$. Note: $Proj_wu = \alpha_1u_1 + \alpha_2u_2 + \alpha_3u_3$, where the $u_i$s are the orthogonal vectors generated in Part (a).\Calculate the error vector $u - Proj_wu$. \$A = (v_1|v_2|v_3)$, that is its columns are the vectors $v_1$, $v_2$, $v_3$. Find the solution $X$ of the system $A^TAx = A^Tu$. \Take $A\tilde{X}$ and compare it with what you got in Part (b). What do you get?

Problem 2 (25 points) For a forward converter, the parameters are given below. Parameters: $L = 300\mu H$, $R = 2.5\Omega$, $12V \le V_{in} \le 24 V$, $V_{out} = 60V$. $T_s = 300\mu s$. The primary winding self-inductance $l_1 = l_2 = 500\mu H$. Coupling coefficients: $k_{12} = 0.99996$, $k_{13} = 0.99994$, $k_{23} = 0.99997$. Ignore the voltage drop on leakage inductance. Answer following questions: assuming the circuit is working in CCM. (5 points) D. Calculate the maximum peak-peak value of the current ripple in the filter inductor E. Please draw the waveform of $\frac{N_2}{N_1}i_L$, $i_{in}$, $v_{D3}$, $v_{s1}$ and the switch status. (5 points)
