Abstract :
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.
