Solutions for a family of the novel three‐level neutral‐point‐clamped (NPC) inductor‐capacitor‐capacitor‐transformer (LCCT)‐derived three‐phase inverters are described and compared. Component design guidelines and steady state analysis, current and voltage waveforms are given. The authors’ simulation results confirm the theoretical predictions. It was found that an asymmetrical three‐level NPC LCCT‐derived inverter with a single diode in the impedance source network is the most promising solution. Experimental results for an asymmetrical three‐level NPC LCCT‐derived inverter with a single input voltage source and continuous input current are presented. The main advantages and design requirements are discussed.
