Question

C. Simulate in PSpice five voltage sources series connected in a such a way that you would have access to the total voltage. For example, Vtotal=V1+V2+V3+V4+V5, where V1=1*sin(120*pi*t), V2=(1/3)*sin(3*120*pi*t), V3=(1/5)*sin(5*120*pi*t), V4=(1/7)*sin(7*120*pi*t), and V5=(1/9)*sin(9*120*pi*t). Plot in the time-domain and in the frequency-domain (use FFT in PSpice) the following waveforms: 1) voltage V1, 2) V1+V2, and 3) Vtotal. It is important to simulate just one period of 60Hz and the plot in the frequency domain should be done from 0Hz to 540Hz.

Answer 1

PSPICE code and result waveform for given circuit as follow

PSPIC code for transeent and frequency analysis of given circuit
V1 1 0 SIN(0 1 60)
V2 2 1 SIN(0 0.333 180)
V3 3 2 SIN(0 0.2 300)
V4 4 3 SIN(0 0.143 420)
V5 vtotal 4 SIN(0 0.111 540)
.tran 0 0.0167 1u
.probe V(*)
.end
