Greetings I am trying to simulate the current through an inductor in a circuit ( See picture. )
The current formula is 169.7*sin(367*t) = 367*(1e-3)* di/dt
I have the intersection of the voltage on the load and vs plotted but cannot figure out how to get the current wave form which is the darkened in one. A fairly common power electronics problem but I cannot figure out how to do in with code
Here is what I have
t = 0:0.01:(2);
Vst = abs(169.7*sind(367*t));
Vd = ones(1,201)*120;
plot(t,Vd,'b')
hold on
plot(t,Vst)
[X0,Y0] = intersections(t,Vd,t,Vst,1)
t_mod = zeros(1,201);
for ii = 1:201
if(t(ii)<=X0(1,1) | t(ii) >= X0(2,1))
t_mod(ii) = 0;
else
t_mod(ii) = Vst(ii)-120;
end
end
I = zeros(1,201);
id = (16.97).*cos(t_mod); % this is where I fail
the intersection program is from the

Awesome program and I have used it many times
Could someone please help get to the very end
Thanks!
