Interests: high frequency PWM and low frequency synchronous optimal modulation for multilevel converters; current quality (THD) theoretical evaluation; natural voltage / current balancing in voltage / current source converters
Neutral Point Clamped (NPC) and Flying Capacitor (FC) converter were introduced 35 and 25 years ago respectively. Since then, multilevel converters became a standard for such applications as medium voltage drives, HVDC grids, and are promising for lower voltage applications, such as battery chargers, active filters, static compensators, dynamic voltage restorers, rectifiers, grid-tied inverters and more. Renewable energy sources and storage systems (photovoltaics, wind generators, batteries, and fuel cells) can feed isolated loads in stand-alone systems using multilevel converters as an interface, with reduced filter requirements. Low voltage MOSFET devices use in multilevel converters with relatively high level count contributes to improvement of efficiency and performance. Increased efficiency and reduced harmonic distortion are beneficial for photovoltaic systems and uninterruptible power supplies. Introduction of multilevel topologies changed power converter design paradigm including control and modulation strategies, components selection and requirements, reliability aspects and more. While relatively low power applications employ high frequency PWM, for high voltage/ current ones the switching frequency of the power semiconductors is limited to few kHz by switching loss considerations and the use of multilevel converters becomes mandatory.
This special issue is intended to motivate further research and development of multilevel converters, refreshing the state of the art, pointing out the benefits of emerging topologies, and investigating novel modulation schemes and for new applications. Original contributions including experimental validation are expected. The topics of interest include, but are not limited to:
- multilevel capacitor based inverter, chopper, and rectifier topologies;
- multilevel inverter modulation strategies and capacitor natural voltage balancing;
- active capacitor voltage balancing including special auxiliary circuits;
- multilevel inverters for renewable energy applications (photovoltaic, wind energy and fuel-cells);
- multilevel converters for high-power electric vehicle battery chargers;
- common mode voltage reduction in multilevel inverters;
- current source multilevel inverters with natural inductor current balancing;
- current source multilevel inverters with active inductor current balancing;
- fault tolerant multilevel converters.
