A parallel inverter for energy saving

A new parallel inverter was designed with a current source model to equilibrate the consumption and compensate the capacitive energy. It uses the oriented field theory in active and reactive power regulation, and the sliding method in the power poles control. The result is an energy transference between AC and DC in both ways without harmonics. The same converter provides connection to photovoltaic cells. A 30-kVA prototype unit is finished.<
