Abstract:
This paper proposes a three-phase multilevel converter topology based on the multiplexed concept which is especially intended for medium-voltage power drives applications. The main potential application are four-quadrant 4.16 kV and 6.6 kV power drives. The proposed topology allows pushing efficiency, switching frequency and cost to values that could not be obtained with HV semiconductors which are expensive and have poor switching performances. This paper will describe the topology, its modulation and control strategy, its main waveforms, the overall efficiency and a comparison with a 5LANPC inverter.
