FPGA Based Control of an Three Level Neutral Point Clamped Inverter

Inhalt:
The accurate control of the line current, the robustness and the dynamic behavior are major factors when benchmarking grid connected inverters. Due to weak grids even fast reactions on distortions and other system faults are required properties. Direct current control in combination with multilevel inverters could combine the advantages and give opportunities for future systems designs. As the complexity, the speed and the calculation effort increases within those systems very fast data processing is indispensable. To meet the mentioned demands Field Programmable Gate Arrays (FGPAs) are an alternative to state of the art Microcontroller Units (MCUs).
