As alternative energy sources become more common, the need for an interface between the energy sources and the existing power generation grid increases. Three-phase inverters are commonly used to convert the dc electric energy generated by alternative energy sources to ac electric energy that is compatible with the utility system .
Figure 1 depicts the circuit architecture for the three-phase grid-connected PV inverters. The PV array, boost converter, DC connection, and inverter make up the inverter. The MPPT controls the boost converter. The transfer of control of the grid’s active and reactive functions is powered by a three-phase inverter. Fig.1.
From tracking the phase, the control of a three-phase inverter can be practically implemented using current control. Given a PLL system and current control algorithm, a Simulink model will be used to simulate the control of a three-phase inverter.
The analyzed topologies of the three-phase inverters were configured to supply a three-phase inductive load (10-Ω resistance in series with 5-mH inductance) from a low-voltage dc supply; an input dc voltage or Photovoltaic Panel of 100 V was assumed for the simulation, whereas 20 V was used in the experimental design.
