I. Introduction
It is well known that, in most applications, a decent amount of efficiency can be gained by replacing a 2-level inverter with a 3-level inverter [6]. Also, by migrating to a 3-level inverter, it is possible to reduce the ripple in the output current or to reduce the filter inductance size [8]. This is the reason that the use of this topology is expected to increase in the fields such as grid connected PV, UPS systems etc.
