Z-source inverter (ZSI) combines the electrical function of a DC/DC converter and a three-phase inverter. This study deals with a three-level neutral-point-clamped (NPC) ZSI which brings an additional electrical potential. The benefit is the lower output current ripple of each phase. Due to the non-linear behaviour of the Z-source control path, designing an accurate and especially a dynamic control can be challenging. This study presents a design of an adaptive control for a three-level NPC ZSI to fulfil the previously mentioned goals. The correct functionality of the control system is underlined with measurements at different operating points. A possible application field for three-level ZSIs are hybrid and electric vehicles.
