A unified power quality conditioner for wide load range: Practical design and experimental results

This paper presents the obtained experimental results with a single-phase experimental prototype of a load compensation active conditioner, sLCAC. The sLCAC is composed by a series-parallel combination of active power filters, to provide a global conditioning of a load against harmonic distortion: to isolate the load voltage v_L from the harmonics in the supply voltage v_S, as well as to regulate it to the nominal value; and also to enhance the supply current i_S, compensating the harmonic and reactive components of the load current i_L. Experimental prototype results with two different types of load are presented to support the performance of the proposed design.
