Paper Details

A voltage-source H-bridge inverter is used to produce the stepped waveform v (t) shown in Figure. For V0 = 50 V, T = 10 msec and D = 0.3:
a. Using Fourier analysis, find the amplitude of the fundamental time harmonic component of v (t).
b. Use the MATLAB 'fit ( )' function to find the amplitudes of the first 10 time harmonics of v(t).
