This paper presents application of fuzzy logic controller for shunt active power filter to improve power quality in the distribution systems. The main feature of fuzzy logic controller does not require any complex mathematical model of the systems to regulate dc bus capacitor voltage. The reference compensating current has been estimated by unit vector template generation technique. The actual ...

This paper presents simplified predictive current controller for 3-ph PWM voltage source inverter connected to the utility grid via filter inductance. By controlling inductance voltage drop, the inverter voltage and hence the injected current can be controlled. The proposed predictive control technique operates with constant switching frequency using space-vector modulation (SVM). In each switc...

In the system, a hybrid active power filters which is the combination of active filter and passive filter. The reference curr...

This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...

Active filters provide significant harmonic and reactive power compensation and are thereby widely accepted as devices for power quality enhancement.. Many research works have been done to improve the dynamic performance of active filters. Current research work focuses on implementing a Minimally Switched Shunt Active Power filter for power quality enhancement. Minimally switched grid interacti...
