Abstract :
This paper presents a repetitive-based controller for an active filter to compensate reactive power and current harmonic distortion in a single phase system guaranteeing a power factor close to unity. The half-bridge topology is selected for the active filter consisting of a single branch of two switches plus a branch of two capacitors on the DC side (split de-capacitor) thus reducing the number of switching devices. The repetitive scheme consists in a negative feedback array plus a feedforward path, and is aimed to compensate for the odd harmonics only. In addition, the controller guarantees the regulation and balance of the two capacitors voltages. Experimental results are presented to show the performance of the proposed solution
