Abstract :
Due to historical reasons, the most diffused solution for electric energy transmission is via fixed voltage and frequency a.c. grids. A 3-phase symmetric supply results typically preferable; anyway, due to practical reasons 1-phase feeders are mostly used for low-power final distribution up to several kVA. This paper deals with a low-complexity converter that was recently proposed to provide a high power quality reversible interface between 1-phase supply and 3-phase loads. Some improvements in the control system are presented, reporting and commenting simulation results showing better performances under nonlinear, unbalanced and variable loads.
