Multifunctional Converter for Single-Phase to Three-Phase Conversion on Rural Grids

This work presents a 10 kW single-phase to three-phase converter, providing an output of 380 Volts rms phase to phase, with power flow control based on droop control. One power leg supply the DC bus and another two power legs generates two aditional phases, to the three-phase loads. The entire circuit with its controls is shown and through simulations are analyzed the interaction between droop control and diferent loads, which regulates the phase connected to the grid, and garantees a balanced sinusoidal voltage for the two other phases. The loads used in the simulations are tipically found in rural areas, such as three-phase motor and a non-controlled capacitive rectifier.
