• In this paper, an analysis of harmonics in the ac and dc sides of voltage-source PWM inverters is presented. The analytical expressions for the total harmonics in the ac side current and in the dc side current and voltage of the inverter as a function of the PWM reference signal are derived. It is shown that, in general, the reference signal which produces a minimum harmonic in the ac side current is different from that which produces a minimum harmonic in the dc side voltage and that they are the same only when the ac side power factor is unity. The total harmonic of the dc side current does not depend on the employed reference signal. From the total harmonic point of view, the addition of harmonics other than the third harmonic into the sinusoidal reference is neither useful nor necessary. Experimental results are included to verify the derived expressions.
