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.
