This paper proposes a multilevel hybrid cascade-stack (HCS) converter. Recently, different new topologies
for cascade-type converters have been suggested with the goal of reducing switch number, loss, switch PIV, etc.
Meanwhile, output voltage steps increase, and the number of switches is predominately reduced in the suggested inverter
in comparison to conventional cascade converters. Additionally, a reduction in the number of on-state switches in
the introduced topology causes power loss and voltage drop to decrease. Firstly, the fundamental parts of inverter
configuration are described. Afterwards, symmetric and asymmetric converter types are discussed. Simulation and
experimental results for 11- and 23-level symmetric types and a 31-level asymmetric form of converter are described.
