For grid-connected inverters, especially the high power rated with low switching and sampling frequency, the output current is severely affected by grid voltage distortion, grid impedance variation and time-delay in the con-trol loop .
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.
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.
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.
The user must not touch the board at any point during operation or immediately after operating, as high temperatures may be present. 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.
TI recommends to use a controlled source at the output, such as an AC power supply to verify grid connected operation. Once the operation is verified, check the functioning of the inverter with direct grid connection. Bias supply to the board is provided by an isolated 15-V supply connected to J2 and S1 in the ON position. Figure 32.
