What is the control design of a grid connected inverter?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.
Why are grid connected inverters prone to Volt-Age oscillations?Due to the inherently low inertia of inverters, there is a heightened risk of disruptive volt-age oscillations. A particular challenge in the operation of grid connected IBRs is the variations in the grid side voltage. The changes in the grid side voltage introduces nonlinear and time-varying constriants on the inverter voltages themselves.
