Multilevel Inverters and Converters

The Power Electronic Building Block (PEBB) concept is to provide generic building blocks for power conversion, regulation and distribution with control intelligence and autonomy. A comprehensive modeling and analysis of a PEBB based DC distribution power system (DPS), comprising of a front end power factor correction (PFC) boost rectifier, a DC-DC converter and a three phase four leg inverter, is performed. All the subsystems of the DC DPS are modeled and analyzed for stability and good transient performance. The effect of impedance overlap on the system and individual subsystems is examined. Ability of a PEBB based converter to stabilize the integrated system by actively changing the system bandwidth is presented.
