FAQS 4
How a grid connected inverter works?
Every algorithm for grid-connected inverter operation is based on the estimation or direct measurement of grid voltage frequency and phase angle. The detection method used in this implementation for a single-phase inverter is based on a synchronous reference frame PLL. Single-phase inverters require a virtual bi-phase system.
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.
How many control levels does a grid-side inverter have?
The strategy consists of 2 coordinated control levels: 1. AC Level Control Manages the grid-side inverter to provide positive and negative sequence voltage support while limiting overcurrent and DC-link voltage oscillation.
Can a grid connected inverter be left unattended?
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.
