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.
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.
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.
This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
