Abstract :
This paper presents a multilevel converter with regeneration capability. The converter is based on the series connection of several power cells, each working with reduced voltage and with an active front end at the line side. This paper presents the control method of each cell, the use of phase-shifting techniques to reduce the current distortion and criteria to select the connection of the cells. The converter generates practically sinusoidal currents at the load and at the input and works with very high power factor
