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.
Since the grid current injected into the grid must be of high quality, many researchers proposed various methods to control the current and suppress harmonics [2, 3]. Linear controllers of four types are commonly used for grid current control.
The inverter control methodology is based in two cascade loops: a fast internal current loop and a slow external voltage loop. The current loop controls the grid current and it effects the current protection and the power quality levels.
