The Dynamic Voltage Restorer (DVR) is a commercially available, popular device to eliminate voltage sags and swells in the distribution lines. Its basic function is to inject the voltage difference (difference between the pre-sag and sag voltage) to the power line and maintains the pre-sag voltage condition in the load side. The efficiency of the DVR depends on the performance of the efficiency...

This article introduces a floating capacitor single stage DC-AC inverter inspired in the flying multilevel cell. A basic structure for MPPT was elaborated applying incremental conductance algorithm acting phase angle of sinusoidal PWM reference. The control strategy simulated MATLAB/Simulink software 6.3 kWp photovoltaic panel and results have validate converter proposition with harmonic curren...

This paper deals with sampled feedback strategies applied on the class of switched affine systems without common equilibria. A distinctive feature of these systems is a cyclical behavior in steady state. From the existence of a Control Lyapunov Function for a relaxed control problem, a novel procedure enabling to compute global attracting sets for the whole system trajectories is exhibited. Thi...

This paper presents a modulator with an active voltage balancing control for the three-phase fourlevel FLC converter based electric motor drive for applications supplied directly from a 6 kV ac-grid. It describes a modulation algorithm of the FLC converter by using the phase shifted PWM modulation with balancing voltage of the flying capacitor by using P controllers in the closed loop. The prop...
