High-Performance 3-Phase 5-Level E-Type Multilevel–Multicell Converters for Microgrids

This paper focuses on the analysis and design of two multilevel–multicell converters (MMCs), named 3-phase 5-Level E-Type Multilevel–Multicell Rectifier (3Φ5L MMR) Inverter MMI) to be used in microgrid applications. The proposed multilevel rectifier inverter have each phase being accomplished by combination I-Type topologies connected T-Type topology. cells are interleaving using an intercell transformer (ICT) order reduce volume output filter. Such topology arrangement is expected allow both high efficiency power density required for applications, as well capable providing good performance terms quality voltage current waveforms. hardware control interface supported simulation results performed Matlab/Simulink. has been then validated experimental campaign converter prototype, which presented a 8.4 kW/dm3 specific 3.24 kW/kg. showed that can achieve peak 99% only silicon semiconductors.
