Abstract :
The present paper deals with isolated neutral multilevel inverters. The topologies of well known structures, that are H-bridge, Neutral Point Clamped (NPC) and Flying Capacitors (FC) are presented with their main features. Computer simulations for all cited topologies are performed and respective waveforms are analyzed. As unusual, it is proved that, for a given inverter number of levels the calculated THDs for phase voltage and line to line voltage are the same.
