Fourier analysis of single-phase full-bridge unipolar inverter

[JinsIG]

Hi, dear friends,

I am simulating the single-phase unipolar inverter. I need to simulate the Fourier analysis up to 5kHz and 4 harmonics, but the simulator always mentions "Wavelength is longer than time span". Could anyone help me to display first four harmonics? Thanks for the help and the files are attached
