The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter.
Additionally, novel PV inverter control techniques ensure stable operation during unbalanced grid conditions using 4-leg NPC inverters, instantaneous active/reactive control, and hardware-based solutions. Table 16 provides a comparative analysis of these control strategies.
Observe the current that is shared on the load by the inverter, and the AC source. Spiking around the zero crossing can occur. These spikes may be mitigated by the user by selecting a different inverter configuration, or using a different modulation scheme. The verification of the grid connected mode of operation is complete.
