Investigations on Three Phase Five Level Diode Clamped Multilevel Inverter

Multilevel inverters have become more popular over the years in high power electric applications without use of a transformer and with promise of less disturbance and reduced harmonic distortion. This work proposes three phase five level Diode Clamped Multilevel Inverter (DCMLI) to simulate various modulating techniques for induction motor load. These Pulse Width Modulation (PWM) techniques inc...

Modeling, simulation and control of three-phase three level multilevel inverter for grid connected photovoltaic system

This paper presents a control for a three phase three-level neutral point clamped inverter (NPC) for grid connected photovoltaic (PV) system. The maximum power point tracking (MPPT) is capable of extracting maximum power from the photovoltaic (PV) array connected to each DC link voltage level. The MPPT algorithm is solved by Perturb&Observe method. The MPPT system is integrated with the DC-link...
