FPGA control of the neutral point clamped quasi-Z-source inverter

The three-level neutral point clamped quasi-Z-source inverter has been proposed recently. Due to its features the neutral point clamped quasi-Z-source inverter is especially suitable for renewable energy sources. This topology requires special control methods and respectively new element basis can be used for control implementation. Current paper describes the control system implemented, based on FPGA for a three-level neutral point clamped quasi-Z-source inverter and the control signals obtained.
