Multilevel inverter have been attracting increasing interest recently due to the increased power rating, improving harmonic performance, and reduced electromagnetic inference (EMI) emission. A voltage source inverter is commonly used to supply a variable frequency variable voltage to a three phase induction motor in a variable speed application. The output voltage contains harmonics the differe...

This paper presents a model predictive control (MPC) of a utility interactive three phase inverter (TPI) for a photovoltaic (PV) system at commercial level. The proposed model uses phase locked loop (PLL) to synchronize the TPI with the power electric grid (PEG) and performs MPC control in a dq reference frame. TPI model consists of a boost converter (BC), maximum power point tracking (MPPT) co...

In this paper a new SVPWM technique is implemented along with multilevel inverter topology for a four-pole induction-motor drive; which is constructed using the induction-motor stator winding arrangement. In this process we are comparing with the conventional five-level inverter topologies so we are a single dc source with a less magnitude therefore, the power balancing problem are reduced. As ...
