Technical FAQs 4

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.

Do grid-connected inverters need injected grid current regulator and active damping?

Abstract: The injected grid current regulator and active damping of the LCL filter are essential to the control of LCL-type grid-connected inverters.

How to control grid current?

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.

How does inverter current control work?

Fortunately, inverter current control has an underlying advantage that the feedback variable, i.e., the inverter current, contains the information of the capacitor current. Naturally, an intuitive idea comes into mind, which is to compute or extract the capacitor current from the sensed inverter current to serve as the damping variable.
