The paper examines and compares the dynamic characteristics of a single-phase voltage inverter with bipolar reverse modulation and unipolar reverse modulation. The equations of motion of single-phase inverters with bipolar reverse modulation and unipolar reverse modulation in dimensionless form. The results of numerical calculations of dynamic modes of the inverter with bipolar reverse modulation and unipolar reverse modulation for different values of the gain. Analysis of the dynamics of the inverter with bipolar reverse modulation showed that by increasing the gain of the output of high-frequency oscillations occur with a frequency pulse-width modulation and a further increase in the gain of the high-frequency oscillations become chaotic. Investigation of the dynamics of the inverter with unipolar reverse modulation showed that under the same gains harmonic distortion of the output signal from the inverter with unipolar reverse modulation is lower than that of the inverter with bipolar reverse modulation.
