This paper discusses a rectifier inverter composed of two three-leg converters with equal and unequal dc-links voltages connected in series. The operation with equal dc-links voltages divides equally the voltages in each converter. On the other hand, the operation with unequal dc-links voltages increases the number of voltage levels and contributes to reduce harmonic distortion and power losses. Space-vector and level-shifted techniques are discussed. The balance of separated dc sources using… CONTINUE READING
