Optimization and comparison of two three-phase inverter topologies using analytic behavioural and loss models

This paper deals a computer-based integrated design and optimization approach of power electronic circuits which is adapted to two inverter topologies, namely the six-pulse (B6) and the Bipolar Switched Neutral Point Clamped (BSNPC) topology. The approach comprises apart from the optimization method itself the analytic behavioural modelling of the topologies and the loss modelling of the devices. The model results are verified by measurements.
