| Abstract |
This paper proposes the use of inductors to implement a single DC link interface in a cascaded
multilevel converter. The positive DC rails of consecutive converter are connected via a single
inductor. This may eliminate the need for separate DC links normally required in applications
demanding the exchange of active power. The operation principle of this novel multilevel converter
topology is presented in detail and its performance verified both by simulation and experimental
results from a 5-level, low power prototype. The current converter rating, compared with a standard
cascaded converter, and the sizing of inductors is also addressed. |
