Abstract :
This work presents a basic unit for a medium voltage multilevel inverter, capable of regeneration of power from the load to the three-phase source. This basic cell uses a single-phase PWM rectifier to reduce the input current harmonics. The work is focused on the control, modeling and simulation of the regenerative cell, which generates practically sinusoidal currents at the output and at the input and works with near unity power factor. Experimental results obtained in the series parallel connection of two regenerative cells confirm the simulation studies
