Symmetrical hybrid multilevel Dc-Ac converters using the PD-CSV modulation

In this paper will be studied the phase disposition (PD) modulation with application of the modulation known as centered space vector (CSV PWM) to the hybrid multilevel symmetrical inverter . Using the generated distortion rate obtained, a comparison with the PSD modulation originally applied is made. The article included the results of an experimental low-power prototype with its fast switches operating at 1.6 kHz and the slow switches operating at 50 Hz. The control circuit is implemented with DSP.
