You did not give value for $V_s$ and for what range of wt. So I made one up

vs=1;
t1=30.45 Degree;
t2=54.28 Degree;
t3=67.1 Degree;
v0[wt_]=4 vs/Pi Sum[  Sin[k wt]/k  (Cos[k t1]-Cos[k t2]+Cos[k t3]),{k,1,Infinity,2}]

Plot[v0[wt],{wt,0,360},Exclusions->None]


 Plot[v0[wt],{wt,0,2 Pi},Exclusions->None]


• Oh...my mistake...let Vs=1. Apr 23, 2017 at 7:51
• wt range is from 0 to 360 Apr 23, 2017 at 7:52
• Thank you ....it works..after this how can we perform Fourier Transforms on the output waveform....i.e, how can we find the frequency spectrum of the output waveform.....the frequency spectrum will be another plot or graph of frequency (x-axis) versus amplitude(y axis) Apr 23, 2017 at 8:58

• Also why dots on the x-axis are not shown in the above solution graph? Apr 23, 2017 at 12:15
