With respect to a traditional two-level inverter, the proposed solution reduces the common-mode voltage (CMV), both in amplitude and frequency. Between the dc source and the traditional three-phase bridge, two active dc-decoupling devices and a voltage-clamping network have been added. A dedicated control strategy was developed adopting a modified space vector pulse-width modulation, oriented to the reduction of the CMV. Simulations showing the good performance of the solution are presented. A preliminary prototype was developed and experimental results are presented. 4950 https://doi.org/10.1109/TIA.2016.2581763$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8-publ-21062$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/publ_mods_00002106 5051 621.3 5550 active DC-decoupling devices 5550 bridge circuits 5550 Bridge circuits 5550 CMV 5550 Common-mode voltage (CMV) 5550 common-mode voltage reduction 5550 DC source 5550 DH-HEMTs 5550 drives 5550 electric drives 5550 electric drives 5550 H8 5550 H8 inverter 5550 inverters 5550 Inverters 5550 leakage current 5550 leakage currents 5550 leakage currents 5550 Leakage currents 5550 Pulse width modulation 5550 pulse-width modulation (PWM) 5550 PWM invertors 5550 space vector (SV) 5550 space vector pulse-width modulation 5550 three-phase 5550 three-phase bridge 5550 Topology 5550 two-level three-phase inverter 5550 voltage-clamping network
