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.
This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
The inverter is interfaced to the grid via an LCL filter. A relay is used to connect and disconnect the inverter from the grid whenever required by the application. The schematic in Figure 11 shows the filtering and relay schematic section.
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.
