In this work, application of two different control strategies to three-phase DC-AC PWM inverter used in smart microgrid system, is analyzed.
In this paper, the design and prototyping of a three-phase inverter that converts DC signal into 3-phase AC signal is presented, which generates 223V square signals at each line from a 12V battery using PWM driven three stages of 18 power MOSFETs, keeping 120-degree phase displacement among the phases.
The three-phase inverters are each rated to deliver 15kW. Two of the inverters (inverters 1 and 2) are connected to energy-storage devices (modeled as dc-voltage sources for the time scales investigated), and one inverter (in- verter 3) is interfaced to a PV array which is modeled using the single-diode model .
