Some problems with connecting renewable energy sources to the grid
... In this section, the details of how to implement a synchronverter will be described. A simple DC/AC converter (inverter) used to convert DC power into three-phase AC (or the other way round) is shown in Figure 3. It includes three inverter legs operated using pulse width modulation (PWM) and LC filt ...

Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same line to ground voltage because it uses less conductor material to transmit electrical power.The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström and Nikola Tesla in the late 1880s.
