Three-phase voltage-source inverters are becoming widely used in grid applications, due to the increased utilization of renewable energy resources such as photovoltaic (PV) systems. The connection of the inverter to the grid must not deteriorate the voltage quality at the point of the common coupling (PCC). Therefore, the injected current harmonics must not exceed certain level. Reduction of the injected...
The switching frequency at which the inverter operates is an important parameter that significantly affects the operation of the inverter. In this paper, a new variable switching frequency algorithm is proposed in which the switching frequency is varied in response to the variation in the operating conditions. The proposed algorithm is based on multi-objective optimization problem formulation such...
