Abstract
This work investigates a general comparison of power loss between the neutral point clamped (NPC) and the multi-neutral points (MNP without clamping diodes) inverter models. Our goal in this study was to compare their respective efficiencies. For an NPC, four devices induce power losses: the switching devices (conduction and switching), the anti-parallel diodes, the clamping diodes and the DC link capacitors. For an MNP model, we have the same electrical devices for each phase except the clamping diodes. In this article, we discuss about two series of equations to estimate the power losses in NPC and MNP models. Finally, we present simulation results.
