<span>This paper presents an analytical comparison between two-level inverter and three-level neutral point diode clamped inverters for electric vehicle traction purposes. The main objective of the research is to declare differences in performance two schemes terms switching conduction losses over entire domain modulation index phase angle distribution, steady-state operation, transient o...

A dual two-level inverter fed open-end winding induction motor drive with a single DCpower supply is proposed. The proposed scheme produces voltage space vector locations identical to those of a conventional three-level inverter. In the conventional neutral-clamped three-level inverter, the series-connected DC link capacitors carry the load current, resulting in a fluctuating neutral point. Als...

The main objective of this research is to build and control a three-phase induction motor using the ANSYS Simplorer Maxwell2D program obtain high-quality sinusoidal voltage profile with little distortion therefore low harmonics. A circuit has been proposed diodes speed by v/f method. This method depends on principle changing source in addition frequency fixed ratio best working conditions chara...

Multilevel converters have seen rising demands in the past decades, due to their increased power ratings, enhanced quality, low switching losses and reduced electromagnetic interference. Prominent among them are three-level (3L) neutral point clamped flying capacitor inverter topologies along with derivatives. Nevertheless, main drawback of these is requirement a front-end boost DC–DC converter...

The standard solution for the traction system in battery powered electric vehicles (EVs) is a two-level (2L) inverter feeding a three-phase motor. A simple and effective way to achieve a three-level (3L) inverter in battery-supplied electric vehicles consists of using two standard three-phase 2L inverters with the open-end winding connection of standard three-phase ac motors. The 3L inverter so...
