Demand of cascaded multilevel inverters in industries electric drives and renewable energy is increasing due to their large-scale capacity high voltage. The modulation technique significantly affects the power quality inverter output This paper proposes a new method carrier wave using phase shift keying for inverters. constant frequency changed at an accurate time by input sinusoidal control si...
In this survey paper, typical solutions that focus on the reduction in negative effects resulting from common-mode voltage influence AC motor drive applications are re-examined. The critical effectiveness evaluation of considered methods is based experimental results tests performed a laboratory setup with an induction machine fed by inverter. capacity level and gradient du/dt limitation discus...
This article proposes an intensive study for common-mode voltage (CMV) elimination/reduction in a five-level dual T-type multilevel converter (MLC) drive. An advanced and fast model predictive control (MPC) approach is developed CMV reduction (CMVR) elimination based on the preselection of switching states (SS). In addition, proposed considers torque capacitor balancing drive as essential aspec...
Low voltage op amps with complementary N–P input differential pairs are known to suffer from low common mode rejection ratio due to mismatch errors and the tail current switching between the N and P input stage. To understand the contribution of the systematic and the random common mode gains to the overall common mode rejection ratio (CMRR) we studied three op amp topologies, which use N–P com...
