A single - phase voltage source inverter is controlled in a single pulse - width modulated mode with a pulse width of $${150^0}$$ in each half cycle. Total harmonic distortion is defined as
$$THD = {{\sqrt {V_{rms}^2 - V_1^2} } \over {{V_1}}} \times 100,\,\,\,$$ Where $${{V_1}}$$ is the $$rms$$ value of the fundamental component of the voltage. The $$THD$$ of output $$ac$$ voltage waveform is
$$THD = {{\sqrt {V_{rms}^2 - V_1^2} } \over {{V_1}}} \times 100,\,\,\,$$ Where $${{V_1}}$$ is the $$rms$$ value of the fundamental component of the voltage. The $$THD$$ of output $$ac$$ voltage waveform is
