Abstract :
This work proposes a topology of compensator with the purpose of compensate harmonics and reactive loads or supply the load with balanced three-phase voltages, even when the grid voltage presents harmonics. The topologies have two operation modes. Mode A: acting as shunt active power filter and mode B: acting as ac-dc-ac converter. The model of the system is derived and a suitable control strategy, including the PWM technique, is developed. Experimental results are presented, as well.
