In Three Phase Inverter the voltage is maintained constant at a controlled value, irrespective of the load events. The capacitance across the inverter maintains the constant voltage. Three Phase Inverter:The variable frequency required for the speed control of three phase ac motors is obtained from a Three Phase Inverter.
Therefore an inverter feeding a three phase motor must be capable of providing a variable voltage, variable frequency supply. The required voltage control can be obtained either external to the inverter or within it (Fig. 3.91).
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.
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.
