A family of Z‐source‐based half‐bridge inverters: Topology derivation

IET Power Electronics
Z‐source‐based half‐bridge inverters are a type of Z‐source inverters whose outer stage is a half‐bridge inverter. This paper presents a generalized structure from which 16 configurations can be derived. Once this topology has been introduced, one of the
