Design, implementation and performance analysis of shunt active filter based on a matrix converter

An energy efficient control method of a photovoltaic system using a new three-phase inverter with a reduced common mode voltage

“…Multilevel inverters (MLIs) have been proposed as a means to reduce common-mode voltage (CMV) without increasing the converter's conduction losses [ 14 , 15 ]. While MLIs use more semiconductor switches than two-level voltage source inverters (2LVSIs), these switches have lower voltage ratings [ 16 ]. One of the key advantages of MLIs over 2LVSIs is their improved output voltage and current harmonic performance [ 17 ].…”

“…One of the key advantages of MLIs over 2LVSIs is their improved output voltage and current harmonic performance [ 17 ]. Additionally, MLIs reduce the dv/dt and the maximum peak value of the CMV [ [14] , [15] , [16] , [17] ]. For instance, the dv/dt of a three-level T-type inverter is reduced by 50 % compared to a 2LVSI using the dc and ac coupling techniques described in Refs.…”
