Problem $3\mathrm{.}2$

For the rectifier shown in Fig. $3\mathrm{.}2,$ L is so large that the current $I_d$ is considered to have negligible ripple. Given are $v_s$ is $120$ V $($rms$)$ at $60$ Hz $,$ and the thyristors are turned with a delay angle $.$

$($a$)$ For $L_c=0,V_{dc}=80V,R=10,=0^0,$ sketch and dimension $i_{s2}(t)$ and $v_L(t).$

$($b$)$ For $L_c=0,V_{dc}=80V,R=0,$ determine the value of $.$

$($c$)$ For $L_c=10mH,V_{dc}=80V,R=10,=0,$ sketch and dimension $v_d(t)$ and $i_{52}(t).$
