Power inverters are used to acquire an ac output voltage from a dc power supply. The parallel connection of inverters results in several advantages, like improvement of the system reliability and increasing of the power capacity. The control problem for parallel-connected inverters is proper voltage regulation and equal current distribution. In this paper, a characteristic loci based compensator (Approximate...
In this paper, practical applications of optimal and flexible controlled (OFC) active filters operating under distorted voltages with non-ideal compensator systems are investigated. In the previous works, the compensator system is regarded as an ideal inverter. On the contrary, this paper takes into account a set of important limitations of the real compensators in frequency domain. Some restrictions...
In this paper optimal design of a current regulated-voltage source inverter (VSI) to be used for active filtering applications using game theory based multi-objective optimization methods is approached. The Inverter hysteresis band and the DC bus voltage are considered as design variables, while the average switching frequency and the tracking error are considered as two distinct objective functions...
In this paper an algorithm for optimal design of active power filters using Strength Pareto multi-objective optimization approach is proposed. Some parameters of the repetitive current controller together with the inverter's DC bus voltage have been considered as design variables. Different optimizing pairs of objective functions including THD of the line currents and the transient response of the...
