Rezumat
Problemele de calitate a energiei sunt deosebit de actuale. Compensarea armonicilor de tensiune/curent si
controlul sau compensarea factorului de putere in retelele de medie/joasa tensiune se pot realiza astazi cu ajutorul
convertoarelor electronice de putere. Pentru compensarea armonicilor, se folosesc configuratii bazate pe filtrele active de
putere. Pentru conditionare activa a factorului de putere se pot utiliza convertoarele PWM de tensiune. Utilizind un
convertor dual de tensiune, printr-o conditionare complexa a sa, pot fi rezolvate ambele probleme de calitate a energiei

Abstract
Power quality problems are of high actuality. Voltage and current harmonics compensation as well as control or
compensation of power factor in medium/low voltage grids can be today performed by using intelligent power electronic
converters. Active filter based configurations are used for harmonic compenastion introduced by nonlinear consumers. For
the active power factor conditioning, PWM-controlled voltage converters can be used. To achieve both harmonics and
power factor compensation, we need complex conditioning using intelligent controlled double-sided voltage converters
