Abstract A novel switch‐based Active‐Neutral‐Clamped (ANPC) inverter for low DC‐link voltage is presented in this paper. The proposed ANPC topology minimizes switches and achieves 1.5 times better voltage gain than standard inverters. The main objective of this design is to reduce active switches in the inverter to increase system efficiency.

We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.
