Garan These facts provide a reduction on electromagnetic interference and improve the heat distribution in the converter. All comparators share the same modulator waveform, value of the sinusoidal wave exceeds the triangular carrier; and each unipolar triangular carrier has a shift determined otherwise, it will be low. For applications such as drives, without output filter, there is a reduction of voltage steps in the machine windings, reducing isolation problems, iron losses, the ripple torque and bearing currents. Each group of vectors is formed by 6 vectors shifted by 6 between them. Once the harmonics frequency of 60 Hz, and an rms fundamental output voltage of are obtained, the total harmonic distortion THD can also be V, generating a line-to-line output voltage with nine levels calculated using and a phase-to-neutral voltage with five levels. Interleaved switching of parallel ZVS hysteresis current controlled inverters.
