Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

Inductor switch mode power supplies (SMPS) operated in a discontinuous inductor current mode are used to balance the dc-link capacitor voltages of a diode-clamped five-level inverter. The SMPS concept is extended to charge up and discharge the four dc-link capacitors. Complete diode-clamped five-level inverter operation is implemented, from start-up, charge-up, balance dc-link capacitors in normal operation, discharge, to shut-down, which have not been presented before. Ramped start of a controlled rectifier sourcing a boost converter limits the lowest dc-link capacitor inrush current and control its charging time. SMPS in conjunction with the boost converter are used to control the dc-link capacitor charge-up and discharge times. The proposed inverter complete operation is validated by simulation and practically.
