Passivity-based control of single-phase multilevel grid connected active rectifiers

M. LISERRE
 
The use of the passivity-based control (PBC) properly fits stability problems related to multilevel converters. Two approaches for
the PBC design have been proposed and will be reviewed in the present paper. Particularly the second is developed by splitting the system into n subsystems and controlling them independently. The partition of the multilevel converter is done on the basis of energy considerations. The main advantage of the second approach is the separate control of the different DC-links and a flexible loading capability.
  
Key words: 

H-bridge, passivity based control, PWM technique
